The pointed tip of a prism is known as the:

• A. Apex
• B. Vertex
• C. Peak
• D. Tip

Answer: (A)

Think about the name for a sharp pointed end on a three-dimensional shape. The term used for the pointed tip of a solid is apex. Apex is the standard word for that single pointed end, the place you’d emphasize as the very tip of the figure, much like the top point of a pyramid or cone.

A vertex, by contrast, refers to any corner where edges meet on a polyhedron, and a prism has many such corners. So while those points are real vertices, the word doesn’t single out a single pointed tip like “apex” does. Peak and tip aren’t formal geometric terms for describing the pointed end of a solid; peak is more about mountains or maximum values, and tip is casual language.

So apex is the best answer because it specifically names the pointed end of a solid.
