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).
Best Answer: centroid = concurrent intersection of the medians of a triangle . this is the center of gravity of the triangle . circumcenter = intersection of the perpendicular bisectors of the triangle . this is the center of the circle passing through the vertices orthocenter = intersection of the altitudes
