Classifying Quadrilaterals in the Coordinate Plane: Lesson (Basic Geometry Concepts)

Here you'll learn how to differentiate among parallelograms, rectangles, rhombuses, squares, kites, trapezoids, and quadrilaterals in the coordinate plane.

This video provides the student with a walkthrough on classifying quadrilaterals in the coordinate plane.
