# 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: If two angles are supplementary to the same angle, then they are congruent to each other.

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