Solution
The correct option is A Rectangular surfaces
Prism is a homogeneous, transparent, refracting material (such as
glass) enclosed by two inclined plane refracting surfaces at some fixed
angle called refracting angle or angle of the prism.
It has two triangular bases and three rectangular lateral surfaces which are inclined to each other as shown in the given figure. It has six vertices and nine edges. Since the base of this prism is in a triangular shape, it is called a triangular prism.
In the given figure of prism:
- Triangular bases are PQR and TUS.
- Three rectangular lateral surfaces are PQUT, PTSR, QRSU.
- Six vertices are P, Q, R, S, T, and U.
- Nine edges are RS, PT, QU, UT, ST, US, QR, QP, and RP.
