h�ԘYo�6�� This free triangle calculator computes the edges, angles, area, height, perimeter, median, as well as other values of a triangle. When you find the value of the angle in an equation, which is the angle that is a solution to the equation, you use that as the reference angle to find other angles on the unit circle that will also be solutions to the equation. print(pythagoras(3,4,'x')) print(pythagoras(3,'x',5)) print(pythagoras('x',4,5)) print(pythagoras(3,4,5)).
