A median of a rectangle is a line that passes through a vertex and the midpoint of the opposite side.
The bisector is the line perpendicular to one side of the triangle and which passes through the midpoint of that same side.
The bisectors of the three sides of a triangle are concurrent, the point of intersection is the center of the circle circumscribed by this triangle.
