Check JK V[4-(-2) + [0 - (-7)F or V85
KL = V(9-0+(2- 4)² or V85
So, OJKLM is a rhombus by Theorem 6.20.
Since the slope of JK = or the slope of KI=or
and the product of these slopes is not -1, consecutive sides JK and KL
are not perpendicular. Therefore, 4JKL is not a right angle. So OJKLMS
not a rectangle or a square.
