Question

In general, what can you conclude about a pair of angles that are both congruent and supplementary?

Answer 1

Angles that are both congruent and supplementary each have a measurement that is equal to 90°.

Explanation:

Answer 2

Both angles are right angles.

Explanation:

Supplementary angles sum to 180°. Since we know that both angles are congruent, let's call them x and x. We can write the following equation:

x + x = 180

2x = 180

x = 90°

Therefore, we can conclude that both angles are right angles.
