Parallel Lines and Angles

Published on 08/01/2011

Activity Overview

Students will use TI-Nspire technology to investigate the relationships between two corresponding angles and between two alternate interior angles. At the end of this activity, students should be able to discover that if two parallel lines are cut by a transversal the pairs of corresponding angles and alternate interior angles are congruent.

Before the Activity

Before this activity, students should be conversant with the Parallel Postulate and the concept of a transversal.

During the Activity

See attached files.

After the Activity

After the activity, the teacher should make a connection with the relationship between parallel lines and transversals. Students should be able to discover that if two parallel lines are cut by a transversal, the pairs of corresponding angles and alternate interior angles are congruent.
