Hi
D = {{{sqrt ((x[1]-x[2])^2+(y[1]-y[2])^2))}}}
M(1,1), 
A(-2,5), MA= {{{sqrt(3^2+(-4)^2)}}}=5   m = -4/3  {{{m =(y[2] - y[1])/(x[2] - x[1])}}}
T(3,5),  AT= {{{sqrt(3^2+(-4)^2)}}}=5   m = 0
H(6,1).  TH= {{{sqrt(5^2)}}}=5          m = -4/3
M(1,1),  HM= {{{sqrt(5^2)}}}=5          m= 0
All 4 sides have equal length,opposite sides parallel
adjacent sides are not perpendicular(slopes are NOT negative reciprocals) 
Rhombus but not a Square.
