    Hello, Victoria!

    How do i find the orthocenter of a triangle?

    The orthocenter is the common intersection of the altitudes.


    Code:
                    A
                    o 
                   ** *
                  * *   *
                 *  *     *   E
                *   *       o
               *    *     *   *
              *     *  *        *
             *    → ◊ ←           *
            *    *  *               *
           *  *     *                 *
        B o * * * * o * * * * * * * * * o C
                    D

    Draw altitude AD perpendicular to side BC.
    Draw altitude BE perpendicular to side AC.

    Their intersection is the orthocenter.
