Question

identify the single transformation shown in the diagram: *
dilation
reflection
translation
rotation

Explanation:

• Dilation: Changes the size of a figure. The two triangles in the diagram are of the same size, so it's not dilation.
• Reflection: Flips a figure over a line. The orientation of the triangles (e.g., the direction of their "points") is not a mirror - image flip.
• Translation: Slides a figure without rotation or reflection. The triangles have a change in orientation relative to each other.
• Rotation: Turns a figure around a point. The black triangle appears to be turned (rotated) relative to the purple triangle around a common vertex.

Answer:

Rotation
