Let PAB be a secant to a circle intersecting at points A and B, and PC is a tangent. Which one of the following is correct?

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

Let PAB be a secant to a circle intersecting the circle at A and B. Let PT be the tangent segment. If PA = 9 cm and PT =12 cm, then what is AB equal to?

Tangent Secant Theorem Point E is in the exterior of a circle. A secant through E intersects the circle at points A and B, and a tangent through E touches the circle at point T, then EA xx EB = ET^(2) . Given : (1) A circle with centre O (2) Tangent ET touches the circle at pointT (3) Secant EAB intersects the circle at points A and B . To prove : EA xx EB = ET^(2)
