Question

angle abc measuring 60° is taken by a dilation with center p and scale factor $\frac{1}{3}$ to angle abc. what is the measure of angle abc? type your answer in the box.

Explanation:

Step1: Recall dilation property

Dilation preserves angle - measures.

Step2: Determine the new angle measure

Since angle - measure is preserved under dilation, if $\angle ABC = 60^{\circ}$, then $\angle A'B'C'=60^{\circ}$.

Answer:

$60$
