Angle Relationships Formed by Parallel Lines

Unit 4: Discovering and Proving Angle Relationships
Lesson 3 of 6

Objective: Students will be able to correctly name types of angles and state that these angles are congruent depending on whether the lines cut by a transversal are parallel.

Big Idea: A tracing paper activity allows students to see [through] that that corresponding angles and alternate interior angles are congruent only if the transversal cuts across parallel lines.
