Answer:
1.Angle
2.Linear pair
3.Supplemetary angles
4.Complemetary angles
5.Vertical angles
Step-by-step explanation:
1.since the two rays have a common endpoint and do not lie on the same line,thus its describe "angles"
2.since the non - common sides formed a straight line,thus its a "linear pair"
3.if two angles are supplement,then the sum of their measure is 180⁰
4.if two angles are complement,then the sum of their measure is 90⁰
5.the angles that are formed by two intersecting lines are called "vertical angles"
