Question

identify the transformation that took place. graph of coordinate plane with triangles pqr (black) and pqr (red), and options: a) dilation, b) rotation, c) translation, d) reflection (options labeled a, b, c, d with corresponding radio buttons)

Explanation:

To identify the transformation, we analyze each option:

• Dilation: Changes the size of the figure, but the triangles appear to have the same shape and size, so not dilation.
• Rotation: A rotation would change the orientation around a point. The triangles seem to have a different orientation consistent with a rotation (e.g., around the origin or another point, changing the direction of the sides).
• Translation: Moves the figure without rotating or changing size, but the orientation here is altered, so not translation.
• Reflection: Flips the figure over a line, but the orientation change here is more consistent with rotation than reflection.

So the transformation is rotation.

Answer:

b. rotation
