The video tutorial explains the concept of slicing three-dimensional figures to understand the relationship between 3D and 2D shapes. It uses examples of a triangular prism and a cylinder to demonstrate how slicing these shapes results in 2D shapes like triangles and circles. The tutorial emphasizes the importance of understanding the connection between 3D and 2D shapes.
