Question

question 8 of 10 defg is an isosceles trapezoid. find the measure of ∠g.

Explanation:

Step1: Recall property of isosceles trapezoid

In an isosceles trapezoid, base - angles are equal. That is, $\angle D$ and $\angle G$ are equal, and $\angle E$ and $\angle F$ are equal.

Step2: Identify the angle equal to $\angle G$

We know that $\angle D = 121^{\circ}$. Since $\angle D$ and $\angle G$ are base - angles of the isosceles trapezoid $DEFG$, $\angle G=\angle D$.

Answer:

D. $121^{\circ}$
