# Lesson Plan: Quadrilaterals and their Properties Mathematics

This lesson plan includes the objectives, prerequisites, and exclusions of the lesson teaching students how to classify different quadrilaterals and recognize their geometric properties.

#### Objectives

Students will be able to

• recall the different types of triangles (scalene, right, isosceles, and equilateral) and their properties,
• identify the geometric properties of angles, sides, and diagonals in different types of quadrilaterals, namely, squares, rectangles, rhombuses, parallelograms, trapezoids, kites, and arrowheads, using the properties of triangles,
• classify different types of quadrilaterals according to the geometric properties of their angles, sides, and diagonals.

#### Prerequisites

Students should already be familiar with

• types of angles,
• triangles and their properties,
• identifying geometric information about parallel, perpendicular, and congruent lines from a diagram.

#### Exclusions

Students will not cover

• the sum of the angles in a quadrilateral,
• areas and perimeters of quadrilaterals,
• exterior angle properties,
• symmetry in quadrilaterals,
