I introduce the Perpendicular Bisector Theorem in triangles. We discuss how the point of concurrency is the center of the circumcenter. The circumcenter is the center of the circle that circumscribed the triangle. I finish by working through two examples of finding the circumcenter of a triangle given its three vertices.
