Slicing and Analyzing 3D Shapes

The video tutorial introduces three-dimensional shapes, focusing on their properties such as faces, vertices, and edges. It explains how to slice these shapes to understand their cross-sections, using horizontal and vertical cuts. The tutorial also includes exercises to apply this knowledge through true/false questions, helping students to differentiate between various 3D shapes and their characteristics.

What is the term for the flat surfaces of a three-dimensional shape?

• Vertices

• Edges

• Faces

• Corners
