What are the pair of angles?

Answer 1

Pairs of Angles

1.Complementary Angles

-are two angles together complete a right angle.

*The two angles need not be to be adjacent.

-to find the complement angle subtract the given angle from 90°.

Ex: Give the complement of 65°.

1. 90°-65° =25° (25+ 65=90)

2. 90°-70° =20° (20+ 70=90)

2.Supplementary Angles

-are two angles whose measurements are equal to 180°.

*The angles not also be adjacent.

-To find the supplement angle, subtract the given angle from 180°.

Ex:

1. Give the supplement of 130°.

180°-130°=50°

3.Adjacent Angles

-two angles with a common side and the same vertex.

4.Vertical angles

-are opposite angles formed two intersecting lines.

They have a common vertex but no common side.
