Question

a figure containing ∠bcd is dilated by a scale factor of $\frac{1}{2}$ to form a new figure which contains ∠bcd. ∠bcd measures 124°. what is the measure of ∠bcd? answer attempt 1 out of 999 m∠bcd =

Explanation:

Step1: Recall dilation property

Dilation preserves angle - measures.

Step2: Apply property to given angles

Since $\angle BCD$ and $\angle B'C'D'$ are corresponding angles in a dilation, $m\angle B'C'D'=m\angle BCD$.

Answer:

$124$
