Lesson Plan: Congruent Polygons Mathematics • 8th Grade
This lesson plan includes the objectives, prerequisites, and exclusions of the lesson teaching students how to identify congruent polygons and use their properties to find a missing side length or angle.
Objectives
Students will be able to
- define congruent polygons as polygons whose vertices and sides coincide exactly,
- use the correct notation for congruent polygons with corresponding vertices in the same order,
- understand that congruent shapes have corresponding interior angles and sides that are congruent and use this to solve geometry problems.
Prerequisites
Students should already be familiar with
- geometric concepts such as line segments and angles and their measures,
- sides, vertices, and interior angles of two-dimensional shapes.
Exclusions
Students will not cover
- criteria for triangle congruence.
