Quadrilateral NORA has vertices N(3,2) O(7,0), R(11,2) an A(7,4). Use coordinate geometry to prove that quadrilateral NORA is a rhombus.

We prove that all 4 sides are the same length, using the distance formula:
d =
NO = = = = = =
OR = = = = = =
RA = = = = = =
AN = = = = = =
All four sides are of equal length
