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.

Example:

  Vertices : A(1|0)         B(5|1)         C(3|6)         
     Sides : 5,38516        6,32456        4,12311        
    Angles : 57,5288°       82,2348°       40,2364°       
 Altitudes : 4,0853         3,47851        5,33578        
   Medians : 4,60977        3,60555        5,5            
  Bisectr. : 4,37592        3,51849        5,46225        

 Circumcir.: M(2,40909|2,86364)       ru = 3,19154
  Incircle : O(3,11866|1,96195)       ri = 1,38952

      Area : A = 11        Perimeter : u = 15,8328
