Question

figure abcd is the image of figure abcd under a dilation with the origin as the center and scale factor ½. the angle measure of a is ∠56° before the dilation. what is the measure of angle a? a 56° b 28° c 124° d 62°

Explanation:

Step1: Recall the property of dilation

Dilation is a transformation that changes the size of a figure but not its shape. Angles remain congruent after dilation.

Step2: Determine the measure of ∠A'

Since ∠A = 56° and angles are congruent after dilation, ∠A' = ∠A.

Answer:

A. 56°
