### Description

Parallel Lines & Transversals - Special Angle Pairs:

This lesson introduces corresponding angles, alternate interior angles, alternate exterior angles, same-side interior angles, and same-side exterior angles. It starts with an investigation activity in which students discover properties of corresponding angles. Students learn about angle relationships that occur when a transversal is cut by parallel lines.

Here's what's included:
- Inquiry-based activity for discovering properties of corresponding angles (protractor & patty paper, tracing paper, or tissue paper required)
- A short presentation
- Practice with angles along a transversal
- 2 Warm-ups
- Critical Thinking worksheet
- Algebra Applications worksheet
- Half-sheet Organizers for recording theorems & postulates (can be assembled into a booklet/study guide)

Please take a look at the preview file for more information. Be sure that the problems are appropriate for your students. Critical thinking questions and algebra applications are included.

Zip file contains two PDF files.

### Standards

to see state-specific standards (only available in the US).
Use informal arguments to establish facts about the angle sum and exterior angle of triangles, about the angles created when parallel lines are cut by a transversal, and the angle-angle criterion for similarity of triangles. For example, arrange three copies of the same triangle so that the sum of the three angles appears to form a line, and give an argument in terms of transversals why this is so.
