Question

A cone is sliced such that the cross section is perpendicular to its base and the cross section intersects its vertex.

What is the shape of the cross section?

A. rectangle
B. triangle
C. trapezoid
D. circle

Answer 1

The scenario described above is like dividing a right cone from the vertex down to the center for the base. The polygon that can be formed from the division or in this case slicing is a triangle. Thus, the answer to this item is letter B. 

Answer 2

The shape of the cross-section of the cone is (b) triangle

From the question, we understand that:

The cone is sliced perpendicular to its base

When the cone is presented as a 2-D shape, it forms a triangle

This means that, slicing the cone in a section that is perpendicular to the base of the cone will give a triangle
