Step 1: Plot the points to get a visual idea of what you are working with. Step 2: Prove that the figure is a parallelogram. There are 5 different ways to prove that this shape is a parallelogram. Choose one of the methods. - Show that both pairs of opposite sides are congruent. - Show that both pairs of opposite sides are parallel.
If one pair of opposite sides is equal and parallel in a quadrilateral then it is a parallelogram. Theorem 1: In a Parallelogram the Opposite Sides are Equal. Proof: Given: ABCD is a parallelogram. To Prove: The opposite sides are equal, AB = CD and BC = AD. In parallelogram ABCD, compare triangles ABC and CDA. In these triangles: AC = CA ...
