WebThey're all 3D shapes. 3D shapes are made of vertices, edges, and faces! Vertices are the pointy bits or the corners where edges meet. Edges are the lines around a shape. Faces are the flat sides that you touch when you hold a shape. Let's look at how many vertices, edges, and faces different 3D shapes have. 👇.
