alleryIf the plane cuts through both nappes, the curve of intersection is a:
AHyperbola
BHexagram
CHeptagon
DHemicycle
Answer & Solution
Correct answer: A. Hyperbola
1. Only one conic has two separate branches.
2. It needs both halves of the cone to appear.
3. When the plane cuts through both the nappes, the curve of intersection is a hyperbola.
4. So the answer is a hyperbola.
