Question

The sections cut by a plane on a right circular cone are called as ______

(a) Parabolic sections

(b) Conic sections

(c) Elliptical sections

(d) Hyperbolic sections

I got this question by my college professor while I was bunking the class.

My question is taken from Basics of Conic Sections in section Curves used in Engineering Practice of Engineering Drawing

Answer 1

Correct choice is (b) Conic sections

To elaborate: The sections cut by a plane on a right circular cone are called as conic sections or conics. The plane cuts the cone on different angles with respect to the axis of the cone to produce different conic sections.
