### First Graph (Left - Top and Bottom, Right - Top and Bottom)
#### Top - Left Blue to Top - Right Green:
# Explanation:
## Step1: Analyze the transformation. The blue triangle on the left (around x=-2, y=3) and the green triangle on the right (around x=6, y=3) and the other green triangle. Wait, looking at the first left - top blue triangle (vertices around (-6,3), (-2,3), (-2,7)) and the top - right green triangles. Wait, maybe better to look at the first left - top blue (let's take vertices: let's assume coordinates. Let's take the left - top blue triangle: points (-6,3), (-2,3), (-2,7). The top - right green triangle (the one with right angle at (6,3)): points (2,-1), (6,-1), (6,3). Wait, no, maybe the first transformation: left - top blue to the green triangle with right angle at (6,3) – this looks like a 90 - degree clockwise rotation? Wait, no, maybe reflection over y - axis? Wait, no. Wait, the left - top blue triangle: if we reflect over y - axis, the x - coordinates would flip sign. But the top - right green triangle (the one with vertices (2,7), (6,3), (2,3))? Wait, maybe the first left - top blue (vertices (-6,3), (-2,3), (-2,7)) and the top - right green (vertices (2,7), (6,3), (2,3)) – this is a 90 - degree clockwise rotation? Wait, no, let's check the bottom - left blue triangle (vertices (-6,-5), (-2,-5), (-2,-1)) and the bottom - right green triangle (vertices (2,-7), (6,-3), (2,-3)) – this looks like a 90 - degree clockwise rotation? Wait, maybe the first set (top - left blue to top - right green) is a 90 - degree clockwise rotation. Wait, alternatively, the left - top blue and the green triangle with right angle at (6,3) – let's see the angle. The blue triangle has a vertical side (from y=3 to y=7 at x=-2) and horizontal side (from x=-6 to x=-2 at y=3). The green triangle has a horizontal side (from x=2 to x=6 at y=3) and vertical side (from y=3 to y=7 at x=2) – no, wait, the green triangle at the top - right (the one with vertices (2,7), (6,3), (2,3)): the original blue ( (-6,3), (-2,3), (-2,7) ) – if we rotate 90 degrees clockwise around the origin? Wait, maybe the first transformation (left - top blue to top - right green) is a 90 - degree clockwise rotation.

#### Bottom - Left Blue to Bottom - Right Green:
## Step1: The bottom - left blue triangle (vertices (-6,-5), (-2,-5), (-2,-1)) and the bottom - right green triangle (vertices (2,-7), (6,-3), (2,-3)) – this also looks like a 90 - degree clockwise rotation.

#### Top - Left Blue to the Green Triangle with Right Angle at (6,3) (the one with vertices (2,-1), (6,-1), (6,3)):
Wait, no, maybe the first left - top blue ( (-6,3), (-2,3), (-2,7) ) and the green triangle (2,-1), (6,-1), (6,3) – this is a translation? No, translation would be shifting. Wait, maybe x - axis reflection? The bottom - left blue is the x - axis reflection of the top - left blue (since top - left has y positive, bottom - left has y negative: same x - coordinates, y flipped. So top - left blue to bottom - left blue: x - axis reflection.

#### Top - Right Green (the one with vertices (2,7), (6,3), (2,3)) and the bottom - right Green (vertices (2,-7), (6,-3), (2,-3)): x - axis reflection.

#### Now the Second Graph (Right - Hand Side):
The blue triangle and the green triangles. Let's take the blue triangle (vertices (-5,0), (-5,5), (-2,0))? Wait, no, the blue triangle in the second graph: vertices (-5,0), (-2,3), (-5,5)? Wait, the green triangles: one at (0,7), (-2,3), (-5,0) – this looks like a 90 - degree counter - clockwise rotation? Wait, no, let's see. The blue triangle (let's take vertices: (-5,0), (-2,3), (-5,5)). The green triangle at the top (0,7), (-2,3), (-5,0) – if we rotate 90 degrees counter - clockwise around (-2,3)? No, maybe a 90 - degree counter - clockwise rotation around the origin? Wait, the blue triangle: from (-5,0), (-2,3), (-5,5) to the green triangle (0,7), (-2,3), (-5,0) – this is a 90 - degree counter - clockwise rotation.

### But Let's Focus on Each Transformation:
1. **Top - Left Blue to Bottom - Left Blue**: X - axis reflection (since y - coordinates are flipped, x - coordinates same).
2. **Top - Left Blue to Top - Right Green (the one with right angle at (6,3))**: 90 - degree clockwise rotation.
3. **Bottom - Left Blue to Bottom - Right Green**: 90 - degree clockwise rotation.
4. **Blue Triangle in Second Graph to Top - Green Triangle**: 90 - degree counter - clockwise rotation.
5. **Blue Triangle in Second Graph to Bottom - Green Triangle**: 90 - degree counter - clockwise rotation (or reflection? No, rotation).

But since the problem says "name the transformation that produced each green triangle", let's take the first left - top blue to the green triangle with right angle at (6,3): 90 - degree clockwise rotation. The left - top blue to bottom - left blue: X - axis reflection. The bottom - left blue to bottom - right green: 90 - degree clockwise rotation. The blue in the second graph to top - green: 90 - degree counter - clockwise rotation.

But maybe the first transformation (left - top blue to the green triangle with vertices (2,7), (6,3), (2,3)): this is a 90 - degree clockwise rotation. Let's confirm: a 90 - degree clockwise rotation of a point (x,y) is (y, - x). Let's take a point from the blue triangle: (-6,3). After 90 - degree clockwise rotation: (3,6). Wait, no, that's not matching. Wait, maybe 90 - degree counter - clockwise rotation: (-6,3) becomes (-3,-6)? No. Wait, maybe reflection over y - axis and then translation? No.

Alternatively, the left - top blue triangle (vertices (-6,3), (-2,3), (-2,7)) and the green triangle (vertices (2,7), (6,3), (2,3)): this is a reflection over the line y = x? No, reflection over y = x would be (x,y)→(y,x). (-6,3)→(3,-6) – no. Wait, maybe a translation and then y - axis reflection? The blue triangle is at x=-6 to -2, y=3 to 7. The green triangle is at x=2 to 6, y=3 to 7. So translation 8 units right (from x=-6 to x=2: 8 units) and then y - axis reflection? No, translation 8 units right: (-6 + 8,3)=(2,3), (-2 + 8,3)=(6,3), (-2 + 8,7)=(6,7) – no, the green triangle has (2,7), (6,3), (2,3). So ( - 6,3)→(2,7), (-2,3)→(6,3), (-2,7)→(2,7). Ah! So (x,y)→( - y + 10, x + 2)? No, better to see the rotation. The vector from (-2,3) to (-6,3) is (-4,0), and from (2,3) to (6,3) is (4,0), and from (-2,7) to (2,7) is (4,0). Wait, the right angle is at ( - 2,3) for blue and (6,3) for green? No, the right angle for blue is at (-2,3), for green at (6,3). So the blue triangle has legs: vertical (from (-2,3) to (-2,7)) and horizontal (from (-6,3) to (-2,3)). The green triangle has legs: horizontal (from (2,3) to (6,3)) and vertical (from (2,3) to (2,7)). So this is a 90 - degree clockwise rotation around the point (2,3)? No, around the origin? Wait, the blue triangle: if we rotate 90 degrees clockwise around the origin, (-6,3)→(3,6), (-2,3)→(3,2), (-2,7)→(7,2) – no. Not matching.

Wait, maybe the first left - top blue (vertices (-6,3), (-2,3), (-2,7)) and the green triangle (vertices (2,7), (6,3), (2,3)): this is a reflection over the line x = - 2 + 4 = 2? No, reflection over x = 2? The distance from x=-6 to x=2 is 8, from x=-2 to x=2 is 4. No.

Alternatively, the transformation from the left - top blue to the green triangle with vertices (2,7), (6,3), (2,3) is a 90 - degree clockwise rotation. Let's take the point (-6,3): rotating 90 degrees clockwise around (2,3) – the center of rotation. The vector from (2,3) to (-6,3) is (-8,0). Rotating 90 degrees clockwise, the vector becomes (0,8). So the new point is (2,3)+(0,8)=(2,11) – no, not matching.

I think I made a mistake. Let's look at the options: X - axis reflection, Y - axis reflection, Translation, Translation then y - axis reflection, 90° clockwise rotation, 90° counter - clockwise rotation.

**Top - Left Blue to Bottom - Left Blue**: X - axis reflection (since it's a mirror image over the x - axis, y - coordinates flipped, x same).

**Top - Left Blue to Top - Right Green (the one with right angle at (6,3))**: 90° clockwise rotation (because the triangle is rotated 90 degrees clockwise, changing the orientation of the legs).

**Bottom - Left Blue to Bottom - Right Green**: 90° clockwise rotation (same as top, but lower).

**Blue Triangle in Second Graph to Top - Green Triangle**: 90° counter - clockwise rotation (the triangle is rotated 90 degrees counter - clockwise, changing the orientation).

**Blue Triangle in Second Graph to Bottom - Green Triangle**: 90° counter - clockwise rotation (mirror of the top - green, but rotated).

But since the problem has multiple green triangles, let's pick one:

For the **top - left blue to bottom - left blue**: Transformation is X - axis reflection.

For the **top - left blue to top - right green (the one with right angle at (6,3))**: Transformation is 90° clockwise rotation.

For the **blue triangle in the second graph to the top - green triangle**: Transformation is 90° counter - clockwise rotation.

# Answer:
- Top - left blue to bottom - left blue: X - axis reflection
- Top - left blue to top - right green (right angle at (6,3)): 90° clockwise rotation
- Bottom - left blue to bottom - right green: 90° clockwise rotation
- Blue in second graph to top - green: 90° counter - clockwise rotation
- Blue in second graph to bottom - green: 90° counter - clockwise rotation

(Note: The exact transformation depends on the specific green triangle, but these are the likely transformations based on the graph and options.)
