Triangles by three Points
If you enter the coordinates of the three vertices of a triangle the program computes all exterior and interior magnitudes, i.e. the sides, the angles, the altitudes, the radians and the bisectors of the angles, the circumference and the area as well as the centers and the radiuses of the circumscribed and the inscribed circle of the triangle. In addition the program plots the triangle with its circumscribed and inscribed circle.
