Question

The line perpendicular to a tangent and is passing through the point of contact is called as _____

(a) Perpendicular bisector

(b) Angle bisector

(c) Normal

(d) Tangent

I got this question during an online interview.

I need to ask this question from Drawing Tangents and Normals for Different Conditions of Circle in chapter Geometrical Construction of Engineering Drawing

Answer 1

The correct answer is (c) Normal

The best I can explain: The line perpendicular to a tangent and is passing through the point of contact is called as the normal. The line joining the centre and the point of contact is perpendicular to the tangent and hence can be called as normal to the tangent.
