Angles and Transversals

Activity Overview

Students explore the relationships of angles formed when two parallel or non-parallel lines are cut by a transversal. This activity investigates the terms: Transversal, corresponding angles, alternate interior angles, alternate exterior angles, same-side interior angles, and same-side exterior angles.

Before the Activity

Install the Cabri: Jr. App on the students' graphing calculators using TI-Connect™, a TI Connectivity Cable and the Unit-to-Unit Link Cable

Use the TI-Navigator™ to transfer the attached Cabri Jr. AppVar files to each calculator

See the attached PDF file for detailed instructions for this activity

Print pages 15 - 18 from the attached PDF file for your class

During the Activity

Distribute the pages to your class.

Follow the Activity procedures:

Use the AppVar to go directly to the exploration section

Draw two non-parallel lines cut by a transversal

Drag each line on a point on the line to find conditions when the measures of the corresponding angles are equal

Measure each angle and determine the relationship between pairs of angles

Draw two parallel lines cut by a transversal

Drag the lines and the points on the lines and note the relationship between pairs of angles

After the Activity

Review student results:

As a class, discuss questions that appeared to be more challenging

Re-teach concepts as necessary
