Similarity (Geometry - Unit 10)

Take the next step beyond congruence with this unit on similarity. Everything you will need to explain the concept is here!

This is a unit bundle that currently contains presentation notes, student follow-along notes handouts, glossary, glossary cards, 6 practice worksheets, 6 section quizzes, a study guide, and a unit test (multiple-choice & short-answer versions). Other items will be added over time, and the price will be modified as necessary during this process.

I am and have been a high school Geometry teacher for 20+ years, and all of the content has been used in my classroom.

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.

The topics included are:

1) Ratios & Proportions - including ratios, extended ratios, proportions, extended proportions, and applications

2) Similar Polygons - including recognizing similarity, identifying corresponding parts, scale factors, and finding missing variable values or measures in a polygon

3) Proving Similarity - including angle-angle, side-side-side, and side-angle-side

4) Right Triangle Similarity - including similarity involving altitudes and the resulting proportions

5) Side Splitters & Triangle Angle Bisectors - including special proportional relationships and the requirements for their occurrence

6) Vocabulary - 24 terms/theorems/postulates

The preview contains a sampling of the notes and assessments.
