Orthocenter Calculator

Find the orthocenter of a triangle from three vertices: the intersection point of the three altitudes (perpendiculars from each vertex to the opposite side).

Frequently Asked Questions

What is the orthocenter?

The point where the three altitudes of a triangle meet. The altitude from each vertex is perpendicular to the opposite side.

Can it be outside the triangle?

Yes, for an obtuse triangle. For an acute triangle the orthocenter is inside, and for a right triangle it coincides with the right-angle vertex.

What is the Euler line?

A line that contains the orthocenter H, centroid G, and circumcenter O of a triangle. The centroid divides the segment from O to H in the ratio 1:2.
