• Solid Figures


  Three dimensional objects with length, width, and height that take up space
• Polyhedron


  • A space or solid figure made up of polygonal regions with flat faces and straight edges
• Face


  The flat surface of a three-dimensional figure
• Edge


  The intersection of faces of a three-dimensional figure
