Describing Cross-Sections of a Right Rectangular Pyramid

The video tutorial explains how to describe the cross-sections of a right rectangular pyramid by slicing it at different angles. It introduces geometric concepts such as planes, cross-sections, and the differences between parallel and perpendicular planes. The tutorial provides visual examples to help understand how different slices of a pyramid result in various 2D shapes like rectangles, quadrilaterals, and trapezoids.

What shape results when a right rectangular pyramid is cut with a plane parallel to its base?

How does the cross-section change when a right rectangular pyramid is cut with a plane not parallel to its base?

What is the result of cutting a right rectangular pyramid with a plane perpendicular to its base?
