question 10 of 10

which term describes the red curve in the figure below?

a. ellipse
b. parabola
c. hyperbola
d. circle

Explanation:

Analyze the intersection of the plane and the double cone

The figure shows a plane intersecting one nappe of a double cone. The plane is tilted at an angle that is greater than the angle of the generator line of the cone but not parallel to the base, resulting in a closed, elongated curve.

Identify the resulting conic section

A closed, bounded curve formed by intersecting a cone with a plane is an ellipse.

Answer:

• A. Ellipse (Correct answer)
• B. Parabola
• C. Hyperbola
• D. Circle
