# Lesson Plan: Angle Relationships Mathematics

This lesson plan includes the objectives, prerequisites, and exclusions of the lesson teaching students how to solve problems involving algebraic expressions and equations using the relationships between complementary, supplementary, adjacent, and vertically opposite angles.

#### Objectives

Students will be able to

• identify a pair of complementary angles,
• identify a pair of supplementary angles,
• classify pairs of angles as complementary or supplementary,
• identify a pair of adjacent angles,
• identify a pair of vertically opposite angles,
• find the measure of an angle given its complementary angle,
• find the measure of an angle given its supplementary angle,
• find the measure of an angle given a vertically opposite angle,
• solve word problems using complementary, supplementary, adjacent, and vertically opposite angles.

#### Prerequisites

Students should already be familiar with

• identifying right and straight angles.

#### Exclusions

Students will not cover

• parallel lines and transversals.
