Secant of a circle

CHORD OF A CIRCLE A line segment joining any two point on a circle is called a chord of the circle.

Theorem of external division of chords. If secants containing chords AB and CD of a circle intersect outside the circle in point E, then AE xx EB = CE xx ED Given : (1) A circle with centre O (2) Secants AB and CD intersect at point E outside the circle. To prove : AE xx EB = CE xx DE Construction : Draw seg AD and seg BC
