Identify Relationships
Name a plane that is parallel to plane GKJ.
Answer: Therefore, plane LPN is parallel to plane GKJ.
In order for a plane to be parallel to plane GKJ , it cannot intersect it.

Identify Relationships
Identify a segment that is skew to JN.
Skew lines cannot intersect and cannot be coplanar.
Answer: Therefore, segment LM is skew to segment JN.
Identify Relationships
Identify two sets of points between which a diagonal can be drawn.
Answer: Lines drawn between points G and N and points L and J would form diagonals.
A diagonal connects two opposite points on parallel planes.

Identify Prisms and Pyramids
Identify the solid. Name the number and shapes of the faces. Then name the number of edges and vertices.
Answer: The figure has two parallel congruent bases that are octagons, so it is an octagonal prism. The other eight faces are rectangles. It has a total of 10 faces, 24 edges, and 16 vertices.

Identify Prisms and Pyramids
Identify the solid. Name the number and shapes of the faces. Then name the number of edges and vertices.
Answer: The figure has one base that is a rectangle, so it is a rectangular pyramid. The other four faces are triangles. It has a total of 5 faces, 8 edges, and 5 vertices.
