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).
The incenter is the point of intersection of the three angle bisectors. The angle bisectors of a triangle are each one of the lines that divide an angle into two equal angles. The incenter is the center of the circle inscribed in the triangle.
