A circumconic passing through the orthocenter of a triangle is a rectangular hyperbola. In any acute triangle, the inscribed triangle with the smallest perimeter is the pedal triangle of the orthocenter (the triangle whose vertices are the feet of the perpendiculars from the orthocenter to the sides).
Definition: The point of concurrency of the perpendicular bisectors of triangles is called the circumcenter of the triangle. Theorem 3.1 Concurrency of Perpendicular Bisectors of a Triangle. The perpendicular bisector of a triangle intersect at a point that is equidistant from the vertices of the triangle.
