The main difference between Complementary Angles and Supplementary Angles: Complementary angles are two angles whose sum equals 90 degrees. Supplementary angles are two angles whose sum equals 180 degrees.
Complementary Angles vs Supplementary Angles — Comparison Table
| Basis | Complementary Angles | Supplementary Angles |
|---|---|---|
| Sum of Angles | Total sum is 90° | Total sum is 180° |
| Individual Angles | Each angle is less than 90° | One or both can be 90° or more |
| Example | 30° and 60° are complementary | 100° and 80° are supplementary |
| Geometric Shape | Found in right triangles | Found on a straight line |
| Relationship | Complete a right angle | Complete a straight angle |
Key Points
- Complementary angles always sum to 90 degrees
- Supplementary angles always sum to 180 degrees
- Both pairs help solve angle problems in geometry
- The sum value helps distinguish between the two types
