Triangles by three Points

If you enter the coordinates of the three vertices of a triangle the program computes all exterior and interior properties, i.e. the sides, the angles, the altitudes, the medians and the bisectors of the angles, the perimeter and the area as well as the centers and the radii of the circumcircle and the incircle of the triangle. In addition the program plots the triangle with its circumcircle and its incircle.

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)       r i = 1,38952

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