triangle abc is isosceles. what is true about the measure of angle b? it is twice the measure of angle a. it is twice the measure of angle c. it is equal to the measure of angle a. it is equal to the measure of angle c.

triangle abc is isosceles. what is true about the measure of angle b? it is twice the measure of angle a. it is twice the measure of angle c. it is equal to the measure of angle a. it is equal to the measure of angle c.

Answer

Explanation:

Step1: Recall isosceles - triangle property

In an isosceles triangle, two sides are equal and the angles opposite the equal - sides are equal. In (\triangle ABC), the marks on the sides indicate that (AC = BC).

Step2: Identify equal angles

The angles opposite the equal sides (AC) and (BC) are (\angle B) and (\angle A) respectively. So, (\angle A=\angle B).

Answer:

It is equal to the measure of angle A.
