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

geometry 
Christiaan,
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.

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

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

geometry 
Lauren,
thanks
