Rectangular prism
The solid figure that has two congruent polygons as bases and lateral faces that are rectangles is called a prism. Specifically, if the bases are triangles, it is known as a triangular prism; if the bases are rectangles, it is a rectangular prism. The lateral faces connect the corresponding edges of the two bases, forming a three-dimensional shape.
A triangular prism.
No. Their "bases" are at right angles to the rectangles connecting the bases.
A parallelepiped.
Circles don't, but the others do, if you think of squares and rectangles as parallelograms.
