Question

two similar triangles are shown.
δrst was __________, then dilated, to create
δzxy.
○ rotated
○ reflected
○ translated
○ dilated

Explanation:

To determine the transformation, we analyze the orientation of the triangles. $\triangle RST$ and $\triangle ZXY$ have a mirrored (flipped) orientation, which is characteristic of a reflection. Rotation would change the angle of the triangle's position, translation would move it without flipping, and dilation (already mentioned as a subsequent step) scales it. So the first transformation is a reflection.

Answer:

B. reflected
