just want to ask a simple question
a quadrilateral has the vertices A ( 1,4 ), B (9,5 ) , C ( 5,-2) and D (-3,-3). show that the quadrilateral is a rhombus
what i do is find gradient AB, CD, AD and BC.
and then state which and which have the same gradient... and hence the opposite sides are parallel.
is that all i should do?
