Published on 11/03/2005

Activity Overview

This activity allows students to: 1. Identify the pairs of angles formed when a transversal intersects two lines.
2. Measure angles using Cabri® Jr.
3. Identify relationships between pairs of angles when a transversal intersects parallel line

Before the Activity

A definition of transversal should be given to students.

During the Activity

Day 1 - Open the document - Angles and Transversals, send the picture file to the student's calculators. Discuss results with the class
Day 2 - Open the document - Parallel lines and Transversals, send the picture file to the student's calculators. Dicuss results.
Day 3 - send LearningCheck™: Parallel lines. Check in class or save and grade

After the Activity

Review student results:

  • As a class, discuss questions that appeared to be more challenging
  • Re-teach concepts as necessary
