### Description

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.

### Standards

to see state-specific standards (only available in the US).
Use congruence and similarity criteria for triangles to solve problems and to prove relationships in geometric figures.
Use the properties of similarity transformations to establish the AA criterion for two triangles to be similar.
Given two figures, use the definition of similarity in terms of similarity transformations to decide if they are similar; explain using similarity transformations the meaning of similarity for triangles as the equality of all corresponding pairs of angles and the proportionality of all corresponding pairs of sides.
