Question

practice identifying three - dimensional solids and the two - dimensional figures that created them. which statements are true regarding the prism? check all that apply. the prism has no vertices. the prism has 9 edges. the bases of the prism are triangles. the bases of the prism are rectangles. the prism has 5 faces.

Explanation:

1. Analyze "The prism has no vertices": Prisms have vertices (intersections of edges), so this is false.
2. Analyze "The prism has 9 edges": A triangular prism has 9 edges (3 edges on each triangular base and 3 connecting edges), so this is true.
3. Analyze "The bases of the prism are triangles": The given prism is a triangular prism, so its bases are triangles, true.
4. Analyze "The bases of the prism are rectangles": Bases of a triangular prism are triangles, not rectangles, false.
5. Analyze "The prism has 5 faces": A triangular prism has 2 triangular bases and 3 rectangular lateral faces, total 5 faces, true.

Answer:

• The prism has 9 edges.
• The bases of the prism are triangles.
• The prism has 5 faces.
