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
