Question

prove that the lenght of the tangents drawn from an external point to a circle are equal​

Answer 1

Answer:

Infinitely Equal because a line can be extend infinitely .....

Answer 2

Explanation:

Given:a circle with centre O

a point p laying outside the circle

two tangents PQ and PR on a circle P

To prove PQ =PR

CON join OP ,OQ AND OR

PROOF OQ=OR (radii of the same circle)

OP=OP (common)

∆OQP=~ ∆ORP(RHSL

PO=PR (CPCT)

the length of tangents drawn from an external point to a circle are equal
