The **CIRCUMCENTER** that a triangle is the point in the planeequidistant native the three vertices the the triangle. Since a point equidistantfrom 2 points lies top top the perpendicular bisector the the segment figured out bythe two points, the Circumcenter is top top the perpendicular bisector of each sideof the triangle.

Notice that the Circumcenter isalso sometimes outside the triangle and also sometimes within the triangle.

The **INCENTER** the a triangle is the allude on the internal of thetriangle the is equidistant indigenous the 3 sides. Since a allude interior come anangle the is equidistant from the 2 sides the the edge lies top top the anglebisector, then the Incenter must be on the edge bisector of each angle that thetriangle.
