Relationships in Triangles (Geometry - Unit 7)

Just when you thought you knew all there was to know about triangles - in comes this tremendous unit all about special relationships that occur in triangles. There are so many gems inside. It would be a shame to miss out. Get it now, and you will agree it is a keeper!

This is a unit bundle that currently contains presentation notes, student follow-along notes handouts, glossary, glossary cards, 6 practice worksheets, 5 section quizzes, a study guide, and a unit test. 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) Midsegments - including how they relate to the third side of a triangle and how to use them to find missing angles/sides

2) Special Segments - including angle bisectors, perpendicular bisectors, medians, and altitudes

3) Special Centers - including incenters, circumcenters, centroids, and orthocenters

4) Inequalities in Triangles - including ordering angles/sides in a triangle, determining if 3 values can represent sides of a triangle, and using the Hinge Theorem

5) Vocabulary - 34 terms/theorems/postulates

The preview contains a sampling of the notes, assessments, and practice.
