Question

Maximum number of tangents that can be drawn from an external point to a circle is ______ .

Answer 1

The tangent of a circle is a special case of the secant when the two end points of the corresponding chord coincide.

From an external point $P$, only two tangents ($PA$ and $PB$) can be drawn.

Also, both the drawn tangents are equal in length.

Hence, maximum $2$ tangents can be drawn from an external point to a circle.
