triangle_distance, a Python code which computes the expected value of the distance between a pair of points randomly selected in a triangle.
This problem is notably more complicated than when the sampling region is a square. In particular, the probability density function for the distance seems to be known only for special cases, such as a right triangle or equilateral triangle.
