Congruence (Geometry - Unit 5) (2024)

Is this triangle the same as that one? How do you know? How can you be sure? What does it mean for them to be the same? All of these questions and many more are answered in this unit on the congruence of triangles and the various details related to types of triangles. You will most certainly want this one in your library of Go-To items for any unit on triangle congruence.

This is a unit bundle that contains presentation notes, student follow-along notes handouts, glossary, glossary cards, 6 practice worksheets, 6 section quizzes, a study guide, and a unit test.

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) Congruent Triangles & CPCTC - including naming congruent figures, identifying corresponding parts, and congruence statements

2) Congruence Theorems - including SSS, SAS, ASA, AAS and why SSA and AAA are invalid

3) Congruence for Isosceles Triangles - including relationships and parts of isosceles triangles

4) Congruence for Right Triangles - including HL and when to use it

5) Congruence for Overlapping Triangles - including identifying overlapping parts and using overlapping triangles to prove other triangles are congruent

6) Vocabulary - 21 terms/theorems/postulates
