Which best describes the orthocenter of a triangle?
A. The point where the three altitudes of the triangle intersect
B. The point where the three medians of the triangle intersect
C. The point where the perpendicular bisectors of the three sides of the triangle intersect
D. The point where the three angle bisectors of the triangle intersect
An orthocenter is where the 3 altitudes intersect. An altitude is a vertical line that drops from a vertex of the triangle to its opposite side in a right angle.
