Slicing 3D Figures

The video tutorial addresses a standardized math test question about slicing 3D figures, specifically a square pyramid. It explains how to slice the pyramid perpendicular to its base through a vertex, resulting in a triangular cross-section. The tutorial guides viewers through the process of understanding the geometric principles involved in slicing and the resulting two-dimensional shape.

What is the significance of the right angle formed during the slicing process?

Explain the process of slicing the pyramid through the vertex.
