Question

How is a Circle formed as a conic section, based on the cutting plane's orientation?
Options
A When the plane passes through the cone, parallel with the base and perpendicular to the axis.
Correct Answer
B When the plane makes the same angle as the elements.

D When the plane intersects the cone parallel to its side (elements).
Correct Answer

Option A is the correct answer.

Detailed Explanation

Page 3 describes a Circle: 'This shape results when a plane passes through the cone, parallel with the base and perpendicular to the axis.'
