Each triangle is isosceles and the side of different length from the other two lengths in a triangle is horizontal.

Of course, each of the isosceles triangles is symmetrical to a vertical line, so it follows that the x-difference of P and Q must be the same as the x-difference of Q and S, if you have correctly identified a vertical line passing through Q as the symmetry line of triangle PQS.

A similar argument applies for the other triangle.
