Activity Overview
In this activity, students learn and increase their knowledge about the angles formed when parallel lines are cut by a transversal. NCTM Geometry Standard covered: Analyze characteristics and properties of 2- and 3-dimensional geometric shapes and develop mathematical arguments about geometric relationships.
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
Set up the
TI-Navigator™ system
See the attached PDF file for detailed instructions for this activity
Print pages 11-12 from the attached PDF file for your class
During the Activity
Distribute the pages to your class.
Follow the Activity procedures:
- Draw parallel lines
- Draw a transversal that cuts both parallel lines
- Explore angle relationships formed by dissecting transversal
TI-Navigator activity:
- Load a background image of parallel lines cut by a transversal with angles named
- Instruct students to identify: the interior, the exterior, to an angle with a specific characteristic (congruent to a given angle, supplementary to a given angle)
After the Activity
Review student results:
As a class, discuss questions that appeared to be more challenging
Re-teach concepts as necessary
