### Orthocenter of Triangle, Altitude Calculation

Calculate the orthocenter of a triangle with the entered values of coordinates. The orthocenter of a triangle is described as a point where the altitudes of triangle meet and altitude of a triangle is a line which passes through a vertex of the triangle and is perpendicular to the opposite side, therefore three altitudes possible, one from each vertex. We can say that all three altitudes always intersect at the same point is called orthocenter of the triangle.
