# Explementary Angles (Mathematics Lesson)

# Explementary Angles

Explementary angles are two angles which add up to a full angle.Two angles that add to 360° are explementary angles.

# A Real Example of Complementary Angles

Angles of 240° and 120° are explementary angles.240° + 120° = 360°.

# How to Find an Explementary Angle

**Question:**What angle forms a pair of explementary angles with the 160° angle below?

**Step 1:**The 160° angle and θ are explementary angles. They add up to 360°.

160° + θ = 360°.

**Step 2:**Subtract the 160° angle from 360°.

θ = 360° - 160° = 200°.

The explementary angle is 200°.
