What to Focus On

  • A polyhedron has flat polygonal faces.
  • Cubes, cuboids, prisms, and pyramids are polyhedrons.
  • Spheres, cylinders, and cones are not polyhedrons.

  • A pyramid has a polygonal base and triangular side faces.
  • A right pyramid has congruent triangular lateral faces.
  • In this chapter, pyramid means right pyramid.

  • Faces are the polygonal surfaces of a polyhedron.
  • Edges are the line segments where faces meet.
  • Vertices are the points where edges meet.

Common Mistakes to Avoid

Any 3-D shape is a polyhedron.

A pyramid can have any kind of slanting faces, so a non-right pyramid still counts the same way in this chapter.

A triangular pyramid has 3 faces because its base is a triangle.
