# If two angles are supplementary to the same angles, then they are ______

Two angles are said to be supplementary angles if they add up to 180 degrees.

## Answer: congruent

Angle 1 and Angle 2 are supplementary, if Angle 1 + Angle 2 = 180^{o}

**Explanation:**

Angles that are equal in the measure are known as congruent angles.

When two angles are supplementary to the same angles, then they are a supplement of the same angle. So, the two angles are congruent.
