Question

what is tangent secant theorem? explain wid fig......

Answer 1

tangents drawn from an external point of a circle are equal

Answer 2

Tangent Secant Segment Theorem: If a tangent and a secant are drawn from a common point outside the circle (and the segments are labeled like the picture to the left), then a2=b(b+c). This means that the product of the outside segment of the secant and the whole is equal to the square of the tangent segment.
