Question

question 2. a student slices a right - circular cone with a plane. if the plane is perpendicular to the base and passes through the apex, what is the shape of the cross - section? a. trapezoid b. triangle c. circle d. ellipse

Explanation:

When a plane is perpendicular to the base of a right - circular cone and passes through the apex, it intersects the cone's lateral surface and the base. The intersection forms a shape with three sides, which is a triangle. The apex of the cone corresponds to one vertex of the triangle, and the intersection with the base circle gives the other two vertices.

Answer:

B. Triangle
