Explanation:
Hello!
- Supplementary angles are angles that add up to 180°
- Vertical angles are opposite and equal angles, formed by the intersection of 2 lines
- A linear pair of angles sum up to 180°, and forms adjacent angles
- Adjacent angles share a common vertex and side
This is all the information we need to fill up the blank spots:
Two angles whose sum is 180° are supplementary angles.
Vertical angles are formed by the opposite angles when two lines intersect.
Vertical angles are congruent/equal/equal in measure.
A linear pair of angles form adjacent angles, and the sum of their measures is 180°.
Adjacent angles share a common vertex and side.
