It's a kite shape and with only 2 angles, they are 30 and 50. The kite is divided into 4 triangles At the front of the kite, one of the angles are 50 (so both vertex angles are 50 degrees)...
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
