Question

two similar triangles are shown. δrst was ________, then dilated, to create δzxy. options: rotated, reflected, translated, dilated.

Explanation:

To determine the transformation, observe the orientation. ΔRST and ΔZXY: the order of vertices (R, S, T) to (Z, X, Y) suggests a reflection (flipping) to align the triangle before dilation. Rotation would change the angle of orientation differently, translation moves without flipping, and dilation is already a subsequent step. So reflection is the prior transformation.

Answer:

B. reflected
