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).
(See picture) 1  If the triangle is obtuse, such as the one on pictured below on the left, then the incenter is located in the triangle's interior. 2  If the triangle is acute, then the incenter is also located in the triangle's interior.
