To construct the altitude of a triangle, you essentially perform a geometric construction of a from a vertex to the opposite side (the base) . Step-by-Step Construction The segment from the vertex to the base line is the
, draw an arc below the base line. Keeping the same compass width, place the point on
). Open the compass wide enough so that when you draw an arc, it intersects the opposite side ( BCcap B cap C ) at two distinct points.
: The orthocenter is exactly at the vertex of the right angle.
