  Glencoe Math Accelerated, Student Edition, Chapter 12.4, Problem 11IP

Calculation:

The faces of a polyhedron are its flat surfaces.

The faces of this pyramid are BCDEFG, ABC, ACD, ADE, AEF, AFG, ABG. Its base is BCDEFG.

An edge is the line segment where two faces intersect.

The edges of this pyramid are BC, CD, DE, EF, FG, BG, AB, AC, AD, AE, AF, AG.

A vertex is a point where edges meet.

The vertices of this prism are A, B, C, D, E, F, G.

Skew lines are lines that are neither parallel, nor intersect one another.

Examples of pairs of skew lines:

   ABand EF.

   BC and AE.

   BG and AF.
