Interior Angles of a Triangle

In this lesson, you will learn how to use the triangle sum theorem to find missing angle measurements.

Objectives

Students will:

  1. Use the triangle sum theorem to find missing angles in a triangle.

Skills Needed

Students must be able to:

  1. Define and identify different types of triangles--equilateral, isosceles, right, obtuse, acute, scalene.
  2. Construct triangles of given angle measures and side lengths.
  3. Recognize and identify when a triangle does not exist due to side lengths or angle measurements.
