BPerpendicular to the base
CParallel to the base
DCurved around the base
Answer & Solution
Correct answer: B. Perpendicular to the base
1. A right prism has a polygon as its base.
2. Its vertical sides stand perpendicular to that base.
3. It is called a right prism because those angles between base and sides are right angles.
4. The base and the top surface are the same shape and the same size.
5. Sides that slant instead of standing upright belong to a pyramid, not a right prism.
