If two segments are tangent to a circle from the same external point, then the segments **are equal to the length.**

if two secants intersect outside a circle, the product of the lengths of one secant and its external length segment equals **Whole X Outside=Whole X Outside.** If a secant and a tangent intersect outside a circle, then the product of the lengths of the secant segment and its external segment equals **Whole X Outside= Tangent².**

If two chords intersect inside a circle, then the product of the lengths of the segments of one chord equals **Part1 X Part2= Part1 X Part2.**
