Quadrilaterals in High School Geometry

Our Quadrilaterals in High School Geometry Quick Reference Guide states all the definitions, postulates, and theorems associated with all quadrilaterals, parallelograms, rectangles, rhombi, squares, trapezoids, isosceles trapezoids, and kites that are found in a typical high school Geometry textbook. Each definition, postulate, and theorem is accompanied by an example that shows exactly what the definition, postulate, or theorem tells you.
