Question

the angle between two tangents to a circle may be 0°. explain this problem with appropriate diagram

Answer 1

if the angle between two tangents of a circle is zero degree then the two tangents will superimpose on each other aur in simple words that two tangents will coincide

Answer 2

Tangent form Zero Angle Between Two Circles

Tangent is a straight line that touches the circle in only one particular point. If a circle intersect each other, and we have to draw tangents on both of the circle with a single line, then there is no way to form angle by the tangents on the circle. It must be zero angular value.
