Properties of Trapezoids and Kites Now that we've seen several types of quadrilaterals that are parallelograms, let's learn about figures that do not have the properties of parallelograms. Recall that parallelograms were quadrilaterals whose opposite sides were parallel. In this section, we will look at quadrilaterals whose opposite sides may intersect at some point. The two types... read more
Quadrilaterals Now that we've taken a detailed look at triangles, we can begin looking at a shape with an extra side and vertex: the quadrilateral. The word "quadrilateral" is composed of two main parts: (1) quad - which means "four", and (2) lateral - which means "side." While triangles are very significant to the world around us, quadrilaterals... read more
Areas of Trapezoids Recall that a trapezoid is a quadrilateral defined by one pair of opposite sides that run parallel to each other. These sides are called bases, whereas the opposite sides that intersect (if extended) are called legs. Let's learn how to measure the areas these figures. Determining the area of a trapezoid is reliant on two main components of these polygons:... read more
