Present how to use slope midpoint and distance formula to determine from the coordinates of the vertices whether a quadrilateral is a parallelogram rectangle square rhombus trapezoid or isosceles trapezoid. Which statement explains how you could use coordinate geometry to prove the diagonals of a quadrilateral are perpendicular. So we use the slope formula on all four sides.

1 Prove the shape is a parallelogram by doing slope 4 times by stating that parallel lines have equal slopes. 1 Prove the shape is a parallelogram by doing slope 4 times by stating that parallel lines have equal slopes. To be able to classify and solve problems with quadrilaterals you need to the definitions of the special quadrilaterals. So we use the slope formula on all four sides.
