Question

Given the points M(-7,-4),N(-3,-3) O(-4,-7) and P(-8,-8). Determine the type of quadrilateral by using coordinate geometry

Answer 1

Try this solution (see the attachment, there is not the only way).

The short explanation: the target - to prove, PN≠OM; PN⊥OM; point S is midpoint of OM&PN, - the properties of rhombus.
