21. Name the geometric figure. The figure is a sphere. LESSON 7-1 Three-Dimensional Figures Additional Examples

23. Example 1-1a Identify the solid. Name the bases, faces, edges, and vertices. Answer: This figure has two parallel congruent bases that are rectangles, GHJK and LMNP, so it is a rectangular pyramid. faces: GHJK, LMNP, GHML, HJNM, JKPN, GKPL edges: vertices: G, H, J, K, L, M, N, P Identify Prisms and Pyramids

24. Example 1-1b Identify the solid. Name the bases, faces, edges, and vertices. Answer: This figure has one triangular base, DEF, so it is a triangular pyramid. faces: DEF, DEG, DFG, EFG edges: vertices: D, E, F, G Identify Prisms and Pyramids

25. Example 1-1c Identify each solid. Name the bases, faces, edges, and vertices. a. Answer: rectangular pyramid base: BCDE faces: ABC, ACD, ADE, AEB, BCDE edges: vertices: A, B, C, D, E

26. Example 1-1d Identify each solid. Name the bases, faces, edges, and vertices. b. Answer: rectangular prism bases: GHJK, LMNP or GKPL, HJNM or GHML, KJNP faces: GHJK, LMNP, GHML, HJNM, JKPN, GKPL edges: vertices: G, H, J, K, L, M, N, P

27. Example 1-2a Identify a diagonal and name all segments that are skew to it. Answer: is a diagonal because vertex Q and vertex W do not intersect any of the same faces; Identify Diagonals and Skew Lines

28. Example 1-2b Identify a diagonal and name all segments that are skew to it. Answer:

29. Example 4-1a 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 faces are rectangles. It has a total of 10 faces, 24 edges, and 16 vertices. Identify Prisms and Pyramids

30. Example 4-2a 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 faces are triangles. It has a total of 5 faces, 8 edges, and 5 vertices. Identify Prisms and Pyramids

31. Example 4-2b Identify the solid. Name the number and shapes of the faces. Then name the number of edges and vertices. Answer: pentagonal pyramid; 1 pentagonal base, 5 triangular faces, 10 edges, and 6 vertices

32. Draw a pentagonal prism. LESSON 7-1 Step 1 Draw a pentagon. Step 2 Draw a second pentagon congruent to the first. Step 3 Connect the vertices. Use dashed lines for hidden edges. Three-Dimensional Figures Additional Examples
