Ok. res = Pick[ ss, (FreeQ[#, [Pi]/2] &) /@ ({VectorAngle[#2 - #1, #3 - #1], VectorAngle[#1 - #2, #3 - #2], VectorAngle[#1 - #3, #2 - #3]} & @@@ ss)]

This work ab = SquaredEuclideanDistance[a, b]; bc = SquaredEuclideanDistance[b, c]; ac = SquaredEuclideanDistance[a, c]; Solve[{ab == bc, bc == ac, ac == ab, m > 0}, m, Reals]

I have just edited $[-10,10]$. I want only integer solutionS. I think, $x$ depend on parameters.
