DRAWING BISECTORS IN A TRIANGLE

What happens if we draw the perpendicular bisector of the three sides of a triangle?

If we draw the perpendicular bisector of the three sides of a triangle we can find a point where the three perpendicular bisectors will intersect. 
The point of intersection of the three perpendicular bisectors is called circumcenter (circuncentro). The circumcenter is also the center of the triangle's circumcircle (circunferencia circunscrita) - the circle that passes through all three of the triangle's vertex. 

 What happens if we draw the angle bisector of the three angles of a triangle? 

 If we draw the angle bisector of the three angles of a triangle we can find a point where the three angle bisector will intersect. 
The point of intersection of the three angles bisector is the incenter (Incentro). The incenter is also the center of the triangle's incircle (circunferencia inscrita)- the largest circle that will fit inside the triangle.
