Three non-collinear points can be grouped so as to form three pairs. Calculate the slopes of the lines that contain each pair of points. If any pair of such lines are perpendicualar, then the triangle is right. Otherwise not. Intersecting lines are parallel if and only if their slopes are negative reciprocals.
