with an inscribed circle


Every step has to be done without errors.

1.- Bisect angle A


 2.- Bisect angle C




3.- Bisect angle B

     The intersection of the three

      bisecting lines is the center of 

      the circle. 

      Label the center O



4.- Place the tip of the compass at

      point O and draw an inside circle

      as shown in step 4.
