Point of Concurrency
The three perpendicular bisectors of a triangle are concurrent.Point of concurrency is called circumcenter.
The circumcenter of a triangle is equidistant from the verticesand is the center of the circle.
The circumcenter of a triangle can be inside, on , or outside a triangle.
Finding the Circumcenter of a triangle.
The point of concurrency of the angle bisectors of atriangle is called the incenter of the triangle.
The bisectors of the anglesof a triangle are concurrentat a point equidistant fromthe sides of the triangle.
P is the center of the circlethat is inscribed in the triangle.
