Question

question 15 (multiple choice worth 1 points) (05.04r mc) what is the shape of the cross section taken perpendicular to the base of a cone? circle rectangle square triangle

Explanation:

A cone has a circular base and a pointed apex. A cross section perpendicular to the base (passing through the apex) will form a shape with three straight sides, matching a triangle. Other options do not fit: circles are parallel to the base, rectangles/squares cannot be formed by this cross section.

Answer:

Triangle
