1-5 Angle Relationships Students will learn how to identify and use special pairs of angles, namely, supplementary, complementary, and congruent (have the same measure).

Type of AngleDefinitionExample Adjacent Angles Vertical Angles Linear Pair Complementary Angles Supplementary Angles

Adjacent Angles Two angles in the same plane. Must have a common vertex and common side. No common interior points. <ABC and <CBD are adjacent.

<ABC and <ABD <ABC and <CBD Adjacent or not?

Linear Pair Pair of adjacent angles with noncommon sides that are opposite rays.

Linear Pair or not?

Name two angles that form a linear pair.

Perpendicular Lines -Intersect to form four right angles -Intersect to form congruent adjacent angles
