Trapezoids,Rhombi,and Kites

LearningObjectives

• Understandthe relationshipsbetweenthe areasof two categoriesof quadrilaterals:basicquadrilaterals
  (rectanglesand parallelograms),and specialquadrilaterals(trapezoids,rhombi,and kites).


• Derivearea formulasfor trapezoids,rhombi,and kites.


• Applythe area formulasfor thesespecialquadrilaterals.

Introduction

We’ll use the areaformulasfor basicshapesto workup to the formulasfor specialquadrilaterals.It’s an
