In geometry, an orthocenter is the point where the altitudes of a triangle meet. An altitude is a line segment drawn from a vertex of a triangle perpendicular to the opposite side. The orthocenter is also the point of concurrency of the three perpendicular bisectors of the sides of a triangle.
The orthocenter is an important point in a triangle. It can be used to find the area of a triangle, the length of the sides of a triangle, and the angles of a triangle. The orthocenter can also be used to construct a variety of other geometric figures, such as circles and squares.
