I suppose you want to know how to construct the orthocenter of a triangle using just ruler and straightedge. To construct the orthocenter you should construct two (three are not necessary) altitudes in a triangle. Their intersection is the orthocenter. You can construct an altitude in a triangle like this: More basic constructions can be found in the Dr. Math archives: http://mathforum.org/dr.math/problems/zaidi11.13.98.html I hope this helps!
