Which Contacts section results from the intersection of the plane and the double nap cone shown in the figure

Mathematics

Answer:

your choice is correct: hyperbola

Step-by-step explanation:

When the plane intersects both naps of the cone, the result is a hyperbola. When only a single nap is intersected (and the plane is parallel to the edge of the cone), the curve is a parabola. An ellipse or circle results when the plane crosses both edges of the cone on the same nap.
