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).
Three angle bisectors. Three medians. Three exterior angles: all three can be obtuse: or one acute and two obtuse: or one right angle and two obtuse. A circumcenter: it could inside the triangle: or outside the triangle; or on the hypotenuse. An incenter. A centroid. An orthocenter. A pedal triangle. Hypotenuse: the longest side of a RAT, opposite the right angle
