In order for a three-dimensional shape to be classified a "prism," its sides must be _________.

rectangles
triangles
parallelograms
circles

ok so ik this is pretty ez but we did this years ago idk why my teacher is puting this as a question and i completly forgot pls help

To determine the sides of a three-dimensional shape classified as a prism, we need to understand the definition of a prism. A prism is a polyhedron with two congruent and parallel bases connected by rectangular or parallelogram-shaped faces.

Therefore, the correct answer is rectangles. The sides of a prism are rectangles, not triangles, parallelograms, or circles.

ok thanks...

Triangles

ever hear of google? It will provide many examples and illustrations.

Actually, none of the choices is always correct. Better research just what is being asked, and just what is considered a "side"
