Understanding 3D Shapes and Properties

In the context of 3D shapes, what is a 'face'?

• A point where edges meet

• A line where two faces meet

• A single flat surface

What are 'edges' in a 3D shape?

• Points where faces meet

• Lines where two faces meet

• Flat surfaces of the shape

• The corners of the shape

What are 'vertices' in a 3D shape?

• Flat surfaces

• Lines connecting faces

• Points or corners where edges meet
