Supplementary Angles
Supplementary angles are pair of angles which have a sum of 180°. To find the supplementary angle of a given angle, simply subtract the given angle from 180°. To find out whether two angles are supplementary, add them and see if they have a sum of 180°. If the sum of the two angles is not equal to 180°, then the angles are not supplementary. Supplementary angles also forms a straight angle.
Answers:
- B.
- R.
- A.
- V.
- E.
Solutions:
1. 180° - 60° = 120°
2. 180° - 80° = 100°
3. 180° - 90° = 90°
4. 180° - 55° = 125°
5. 180° - 150° = 30°
Since supplementary angles have a sum of 180°, all we have to do is to subtract the given angle measures to find its supplementary angles.
