In this lesson you will learn how to identify angle types and how you can use this information to find the measurements of unknown angles.

Objectives

Students will:

  1. Identify and name supplementary, complementary, vertical, and adjacent angles using geometric naming conventions.
  2. Use facts about supplementary, complementary, vertical, and adjacent angles to write and solve simple equations for an unknown angle measurement in a figure.

Skills Needed

Students must be able to:

  1. Use a protractor to measure angles.
  2. Solve one- and two-step equations.
