Question

question a figure containing ∠cde is dilated by a scale factor of 5 to form a new figure which contains ∠cde. ∠cde measures 119°. what is the measure of ∠cde? answer attempt 1 out of 2 m∠cde =

Explanation:

Step1: Recall dilation property

Dilation is a transformation that changes the size of a figure but not the shape. Angles are preserved under dilation.

Step2: Determine angle measure

Since $\angle CDE$ and $\angle C'D'E'$ are corresponding angles and dilation preserves angle - measures, if $m\angle C'D'E' = 119^{\circ}$, then $m\angle CDE=119^{\circ}$.

Answer:

$119$
