Question

probe that the tanhent to a circle at the end points of a diameter are parallel​

Answer 1

DRAW A CIRCLE

DRAW TWO TANGENTS FACING EACH OTHER

JOINT THEM WHERE THE TOUCH THE CIRCLE TO FORM A DIAMETER CONNECTING THEM

A................................O...................................B

●_____________○_____________●

now let suppose a and b are intersection points of tangents

o is centre of circle

let the tangents be l and m

now OA ⊥ tangent l

OB ⊥ tangent m

..........tangent perpendicularity theorem

but OA=OB........radii of same circle

therfore tangent l ll tangent m
