Solution:
Given:
- An angle which measures 51°
Using the given measure of an angle, we can identify all the angles.
- a° = 51° (Vertically opposite angles)
- b° = 180 - 51 = 129° (180° angle)
- d° = b° = 129° (180° angle)
- w° = 129 (Alternate inner angles)
- x = a = 51° (Alternate inner angles)
- z = x = 51° (Vertically opposite angles)
- w = y = 129° 9 (vertically opposite angles)
We can tell that:
- a = x = z = 51°
- b = d = w = y = 129°
Supplementary angles are pairs of angles that sums up to 180°.
Example of supplementary angle:
- ∠a and ∠b are supplementary angles because they sum up to 180°.
