The orthocenter of a triangle is the point of intersection of the three altitudes. To find the orthocenter, start with one side of the triangle and draw a perpendicular line (90 degrees) from that side to the opposite vertex. Repeat this process with the other two sides of the triangle. The three lines will intersect at a single point called the orthocenter.
Draw a perpendicular line on every side, and where all the lines meet is the the othocenter
The orthocenter of a triangle can be found by just drawing perpendicular on every sides and where all the perpendicular lines(altitudes) meets is the orthocenter.
