Circumcenter of a Triangle
The circumcircle of a triangle is the circle that passes through each vertex of the triangle. The circumcenter of a triangle is the center of the circumcircle. The circumcenter is the intersection of the three perpendicular bisectors of the sides of the triangle. If the vertices are only allowed to move around the circumcircle, then the circumcenter never changes position! Drag the locators to move the vertices.
