Unit 9: Quadrilaterals, Area, Surface Area, and Volume


In this unit, you will study quadrilaterals. Specifically, you will look at quadrilaterals with special properties—parallelograms, rectangles, rhombi, squares, and trapezoids. You will compare and contrast the various quadrilaterals, and use them to solve real world applications.
