Which term describes the point opposite the base of a pyramid or cone?

• A. Vertex
• B. Apex
• C. Base
• D. Frustum

Answer: (B)

The term that describes the point opposite the base of a pyramid or cone is "apex." The apex is a specific point that is at the very top of the pyramid or cone, where all the lateral sides meet. In the case of a cone, the apex is the pointed tip above the circular base, whereas, in a pyramid, the apex is the point where the triangular faces converge. Understanding that the apex serves as a defining characteristic of three-dimensional shapes like pyramids and cones is important in geometry, as it helps in recognizing and differentiating these solid figures from others. The other terms refer to different aspects or parts of geometric figures. The vertex typically refers to a point where two or more edges meet in polyhedra. The base is the flat surface on which the figure stands, while the frustum is a section of a solid (like a cone or pyramid) that results from slicing off the top. Each of these terms relates to the figure, but the apex specifically denotes the highest point or tip.
