Question

Prove that tangent drawn at the end of diameter of a circle are parallel

Answer 1

i hope this will help u

Answer 2

let PQ be the diameter of the circle of centre O let AB and CD be the tangents drawn to the circle to the end point of the diameter PQ since the tangent at a point to a circle is perpendicular to radius through the point= PQ perpendicular AB and PQ perpendicular CD
=angle APQ=angle PQD
so, AB || CD
