Triangle Perpendicular Bisectors & Circumcenter

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. ***NOTE: In the final example, m is used for both midpoint and slope. mp should be used for midpoint and m for slope.
