      What is depicted here isn’t even a polygon, let alone a triangle, let alone a right triangle. This is just a line segment. Line AB is the same as line AC. There is no line BC. BC is a single point.

      I suppose it could possibly depict a weird cross section of two orthogonal circles in a real and an imaginary plane.
