There is no direct formula to calculatethe orthocenter of the triangle. It lies inside for an acute and outside for an obtuse triangle. Altitudes are nothing but the perpendicular line ( AD, BE and CF ) from one side of the triangle ( either AB or BC or CA ) to the opposite vertex....
Altitude of a triangle is basically the perpendicular line segment drawn from the vertex to the opposite side of the triangle. The altitude or height of a triangle may lie inside or outside the triangle. Learn with examples at BYJU’S.

The name ‘poly’ refers to multiple. An n-gon is a polygon with n sides; for example, a triangle is a 3-gon polygon. General Formula for Sum of internal Angles of a polygon – \(\begin{array}{l}\text{Sum of internal Angles of a polygon = }(n-2)\times 180\end{array} \) ...
Note that triangle DPE is a right triangle, and that the four angles (angles APC, CPD, DPE, and EPA) that have point P are all right angles. Using the fact that the centroid (P) divides each median in a 2:1 ratio, AP=4 and CP=3. Quadrilateral AEDC is now just four right...
