LAP # 4 Chapter 4 Congruent Triangles

NAME_____________________________________
Essential Questions: What does it mean for two figures to be congruent? How can we prove two
triangles are congruent?
Overview: Congruent figures have the same shape and size. We will learn to prove two triangles are
congruent with four different methods using sides and angles. Isosceles, equilateral, and right
triangles have special theorems to help prove if two triangles are congruent
Rationale: Understanding congruence is very important anytime someone builds. Rockets,
buildings, cars, bridges, tables, and many more important structures must have congruent figures in
order to work properly. If a chair does not have congruent angles and lengths, it will be faulty and
someone could fall out.
Objectives:
- recognize congruent figures and corresponding parts
- prove triangles are congruent using four different methods
- apply properties of isosceles triangles
- prove right triangles are congruent using HL
Enrichment: FACEing Math
