Introduction
This chapter starts with the properties of polygons and narrows to focus on quadrilaterals. We will study several
different types of quadrilaterals: parallelograms, rhombi, rectangles, squares, kites and trapezoids. Then, we will
prove that different types of quadrilaterals are parallelograms or something more specific.
