1. The perpendicular bisectors of the sides of a triangle are concurrent at a point called the
______________________.
2. The point of concurrency is equidistant to_____________________.
The radii of circles made from perpendicular bisectors is often called the circumradius.
3. Repeat this construction with a right triangle. Where is the point of concurrency for this
type of triangle?
