Question

A rectangular pyramid is sliced so the cross section is perpendicular to its base and passes through its vertex. What is the shape of the cross section?

Answer 1

The answer is triangle.

Explanation:

A rectangular pyramid is sliced so the cross section is perpendicular to its base and passes through its vertex.

The shape of the cross section will be a triangle.

A rectangular pyramid is a 3 D object with a rectangular base and a triangular face corresponding to each side of the base. When it is sliced perpendicular to its base and the cross section passes through its vertex, then a triangle is formed.

Answer 2

The answer for the question shown above is: The shape of the cross section is a triangle.

The explanation is shown below:

Imagine that you have a plane that intersect the rectangular pyramid and it passes through its vertex and it is perpendicular to the base of the pyramid, when you look the cut, you will see a triangle as a cross section.
