Alternate Interior Angles

Published on 08/24/2011

Activity Overview

Explore the relationships of the angles formed when two parallel lines are cut by a transversal.

Objectives

  • Students will identify pairs of alternate interior angles and same-side interior angles given two lines cut by a transversal.
  • Students will recognize which pairs of alternate interior angles are congruent.
  • Students will recognize which pairs of same-side interior angles are supplementary.

Vocabulary

  • parallel lines
  • transversal
  • alternate interior angles
  • same-side interior angles
  • supplementary angles
  • congruent angles

About the Lesson

This lesson involves students recognizing which pairs of alternate interior angles are congruent and which pairs of same-side interior angles are supplementary. As a result students will:

  • Click on different segments in order to identify which segments form alternate interior angles and which segments form same-side interior angles.
