Altitude and Orthocenter of a triangle

A triangle has different line segments with an intersection. One of the line segments are the altitude of the triangle.

• An altitude of a triangle is a right-angled line from a vertex to its opposite side

• The altitudes of a triangle can be drawn from any vertex, therefore each triangle has three altitudes

• When the three altitudes of a triangle intersect, their intersection is called an orthocenter

• An orthocenter can lie inside, on or outside the triangle, depending on its angles
