The circumcenter of a triangle is equidistant from the vertices of a triangle.

Circumcenter - the center of the circle that circumscribes the triangle, ie. goes through all its vertices.

circumcenter circumcenter is wrong, it is the incenterbecause the point of concurrency is always on the inside of the triangle.
