Question

What is the name of the point which is common to circle and the tangent?

(a) Intersection point

(b) Tangential point

(c) Point of contact

(d) Point of touch

The question was posed to me in a job interview.

My query is from Tangent to a Circle topic in section Circles of Mathematics – Class 10

Answer 1

The correct answer is (c) Point of contact

To elaborate: A line that touches/intersects a circle at exactly one point of a circle is called a tangent and the point which is common for both circle and tangent is called the point of contact.
