What is an easy way to find the orthocenter of a triangle?

Answer 1

The easiest way to do this is find 2 of the 3 altitudes of the triangle and look where they intersect. This point is the orthocenter.

Answer 2

but don't the altitudes have to be perpindicular to the triangle lines?

Answer 3

Yes they do. An altitude is a line that contains one corner of the triangle and is perpendicular to the side across this corner
