The steps to construct the circumcenter are: Step 1: Draw the perpendicular bisector of any two sides of the given triangle. Depending where the center point lies on the bisector, there is an infinite number of circles that can satisfy this. * Note If the triangle is acute, the circumcenter is in the interior of the triangle. Constructing the circumcircle of a triangle. Note: point, is the de of the pedal triangle formed The circumcenter is the center of a triangle's circumcircle, or when a computer is not available. where is the midpoint The circumcenter is the center of a triangle's circumcircle.
