Two angles whose sum is 180 degrees are called supplementary angles.
Explanation:
- If angle A and angle B are supplementary, then:
A+B=180∘A+B=180^\circ A+B=180∘
- These angles can be adjacent (forming a straight line) or non-adjacent.
Example:
- If one angle is 70°, the other angle will be:
180∘−70∘=110∘180^\circ -70^\circ =110^\circ 180∘−70∘=110∘
So, 70° and 110° are supplementary angles.
