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).
Denote the vertices of a triangle as A, B, and C and the orthocenter as H, and let D, E, and F denote the feet of the altitudes from A, B, and C respectively. Then: The sum of the ratios on the three altitudes of the distance of the orthocenter from the base to the length of the altitude is 1:
