Question

prove that "The lengths of tangents draw from an external point to a circle are equal "​

Answer 1

Step-by-step explanation:

proof==in∆ PAD AND ∆QAD,

SEG PQ CONGRUENT TO QA.....(RADII OF SAME CIRCLE)

SEG AD CONGRUENT TO AD .....(COMMON SIDE)

ANGLE APD= ANGLE AQD=90°....(TANGENT THEOREM)

∆PAD CONGRUENT TO ∆QAD.....(SSA TEST)

SEG DP CONGRUENT TO DQ.....(CSCT)
