alleryThe kind of conic obtained depends on the plane's position and the angle it makes with the:
AVertical apex
BVertical axis
CVertical arc
DVertical arm
Answer & Solution
Correct answer: B. Vertical axis
1. Tilting the cutting plane changes the curve.
2. The tilt is measured against a reference line of the cone.
3. Different conics arise from the position of the plane and the angle it makes with the vertical axis of the cone.
4. So the answer is the vertical axis.
