Properties of Parallel Lines Cut by a Transversal

Activity Overview

In this activity, students create parallel lines and a transversal, and study the properties of the lines and their angles.

Before the Activity

Install the Cabri™: Jr. App on the students' graphing calculators using one of these two methods:

TI-Connect™, a TI Connectivity Cable, and the Unit-to-Unit Link Cable

TI-Navigator™ "send to class" feature

See the attached PDF file for detailed instructions for this activity

Print pages 7 - 9 from the attached PDF file for your class

During the Activity

Distribute the pages to the class.

Follow the Activity procedures:

Draw two parallel lines

Construct a transversal

Label the lines and the points of intersection

Measure and label angle measurements

Prepare a table which lists the pairs of angles, types of angles, and their measures

Observe that the pairs of corresponding angles are equal

Note that the pairs of alternate interior angles are congruent

Identify that the pairs of consecutive interior angles are supplementary

Observe that the pairs of alternate exterior angles are congruent

Drag an intersection point around the screen to verify whether the relationship between angles remains same

After the Activity

Review student results:

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

Re-teach concepts as necessary
