Identify Relationships Name a plane that is parallel to plane GKJ. In order for a plane to be parallel to plane GKJ , it cannot intersect it. Answer: Therefore, plane LPN is parallel to plane GKJ. Example 1
A B C D Name a plane that is parallel to plane QUXT. A. plane QRST B. plane UVWX C. plane QRVU D. plane RVWS Example 1
Identify a segment that is skew to JN. Identify Relationships Skew lines cannot intersect and cannot be coplanar. Answer: Therefore, segment LM is skew to segment JN. Example 2

Identify Relationships Identify two sets of points between which a diagonal can be drawn. A diagonal connects two opposite points on parallel planes. Answer: Lines drawn between points G and N and points L and J would form diagonals. Example 3
A B C D Identify a set of points between which a diagonal can be drawn. A. points S and Q B. points V and X C. points Q and W D. points R and W Example 3
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. Example 4
A B C D Identify the solid. Name the number and shapes of the faces. Then name the number of edges and vertices. A.triangular prism; 2 triangular faces, 3 rectangular faces, 9 edges, and 6 vertices B.pentagonal pyramid; 3 triangular faces, 2 rectangular faces, 9 edges, and 6 vertices C.rectangular prism; 2 triangular faces, 3 rectangular faces, 9 edges, and 6 vertices D.cylinder; 2 triangular faces, 3 rectangular faces, 9 edges, and 6 vertices Example 4
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. Example 5
