PRODUCT DESCRIPTION

Easy to follow guided notes with examples and practice problems for students. Unit 3, Parallel and Perpendicular Lines, covers the following topics:

- Parallel Lines and Transversals
- Angles and Parallel Lines
- Slope
- Equations of Lines
- Proving Lines Parallel
- Perpendiculars and Distance

Product Description

What types of angles get formed when lines cross each other? Being able to recognize this is such an important skill. This unit will help you show your students how to recognize these important relationships and apply them in several scenarios including how they can be used in proofs.

This is a unit bundle that contains presentation notes, student follow-along notes handouts, glossary, glossary cards, 4 practice worksheets, 5 section quizzes, a study guide, and 4 unit tests.

The notes introduce each concept along with a few examples. They are in-depth enough to cover a topic well, and, at the same time, are brief enough to allow you to add related topics/examples of your choice without being overwhelming or stifling your own creativity/flexibility.

1) Angle Pairs with Transversals - including corresponding, same-side interior, same-side exterior, alternate interior, and alternate exterior

2) Parallel Lines with Transversals - including how to use parallelism to determine angle sizes and how to use angle sizes to determine parallelism

3) Relating Parallel/Perpendicular Lines & Triangles - including auxiliary lines, the perpendicular transversal theorem, the triangle angle-sum theorem, the triangle exterior angle theorem, slopes of lines, and ratios of angles within a triangle

4) Vocabulary - 16 terms along with 16 theorems/postulates
