Triangle Orthocenter:

The orthocenter is three altitudes intersect of triangle. If the orthocenter lies inside, It means the triangle is acute.

To find the orthocenter of a triangle with the known values of coordinates, First Find the slope of the sides, then calculate the slope of the altitudes, So we know the perpendicular lines, because the through the Points A B and C, At last, solving any 2 of the above 3 perpendicular lines.

For example, To points A(4,3), B(0,5) and C(3,-6)

The orthocenter is (8.05263, 4.10526).
