Lesson Plan: Applications of Triangle Congruence Mathematics • First Year of Preparatory School
This lesson plan includes the objectives, prerequisites, and exclusions of the lesson teaching students how to use the triangle congruence criteria SSS, SAS, ASA, and RHS to find unknown angles or sides in geometry problems.
Objectives
Students will be able to
- identify congruent triangles by applying the correct congruence criterion,
- use the fact that triangles are congruent to find unknown angle measures and side lengths and solve problems.
Prerequisites
Students should already be familiar with
- triangle congruence criteria.
Exclusions
Students will not cover
- similar triangles.
