Question

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

Answer 1

Hey mate ☺️

Given:-

Tangent AB and AC are on points B and C.

To prove

AB=AC

construction :

join O to A

O to C

and

O to B

proof :-

in triangle aoc and triangle aob

angle oca = angle oba( both 90°)

ob = oc (radius of circle)

oa = oa (common)

hence, triangle aoc congruent to triangle aobv(by rhs)

Hence,

ab = ac (cpct)
Proved!!

I Hope it helps you ☺️✌️✌️
