Question

If two angles are supplementary and congruent, what is the measure of each angle?

100°
180°
90°
45°

Answer 1

90

Explanation:

supplementary angles equal 180 degrees and 90+90=180

Answer 2

90°

Explanation:

Supplementary angles are angles that add up to 180°.

Congruent means the angles are equal to each other.

Since there are two angles, and they have to be equal to each other, we can divide 180° by 2 to find the measure of each angle.

180° / 2 = 90°

Both angles have a measure of 90°.
