Angles are geometric figures which are formed by two intersecting rays. There are different types of angles according to measure and relationship. Acute, right, and obtuse are kinds of angles according to measure. Vertical, adjacent, complementary, corresponding, and supplementary angles are types of angles according to relationship. To understand each type of angles let us go over the definitions below.

Answers:

congruent
complementary, supplementary
congruent
adjacent, 180°
intersecting, right, intersect

Solutions:

1. By definition, congruent angles are angles with the same or equal measurements.

2. By definition, complementary angles are pair of angles whose sum is equal to 90° while supplementary angles are pair of angles whose sum is 180°.

3. By definition, vertical angles are pair of opposite angles which are equal in measure.

4. By definition, linear pairs are adjacent angles whose sum is equal to 180°.

5. By definition, perpendicular lines are intersecting lines that form 90 degree angles while parallel lines are lines that do not meet or intersect.
