Supplementary Angles

Two angles are supplementary if the sum is 180° or radians. So, if two supplementary Angles are added, a straight angle is obtained.

Angles That Differ by 180° or π Rad

Angles Greater Than 360º

Angles That Differ by 90° or π/2 Rad

 

Angles That Add Up to 270º or 3/2 π Rad

 

Angles That Differ by 270º or 3/2 π Rad
