Proving via Coordinates We can also prove that an object is a quadrilateral if we’re given the coordinates of the vertices by • Proving that both sets of sides are congruent • Proving that two sides are congruent and parallel • Proving that both sets of sides are parallel Proving congruency is easy via the distance formula, so let’s look at this one
An example… Find all of the angles given the listed angle measure 130 1 4 2 7 5 8 6 Axis of symmetry Vertex
