Question

these figures are congruent. what is m∠o?

Explanation:

Step1: Recall congruent - triangle property

Corresponding angles of congruent triangles are equal.

Step2: Identify corresponding angles

In congruent triangles $\triangle GIH$ and $\triangle OPQ$, $\angle O$ corresponds to $\angle G$.

Step3: Find the measure of $\angle O$

Since $\angle G = 80^{\circ}$, then $m\angle O=80^{\circ}$.

Answer:

$80$
