Question

The angle between the tangent and the line joining the point of contact of the tangent to the centre of the circle is ______ .

• A. $$0^o$$
• B. $${90}^o$$
• C. $${180}^o$$
• D. $${360}^o$$

Answer 1

The correct option is B $${90}^o$$

$\text{Tangent and the line joining the point}\text{of contact of tangent to centre of circle is}\text{perpendicular to each other.}$

$\text{So, the angle between them is}{90}^o$.
