Question

choose the correct definition.
what is the definition of a prism?
a prism is a polygon with 4 straight sides and four vertices.
a prism is a polygon with three straight sides and three vertices.
a prism is a polyhedron that has one special face called the base, and all the other faces are triangles that meet at a single vertex.
a prism is a polyhedron with two parallel faces that are identical copies of each other, called bases, connected by rectangles.

Explanation:

A prism is a 3D polyhedron. The first two options describe 2D polygons (quadrilateral and triangle), so they are incorrect. The third option defines a pyramid (one base, triangular faces meeting at a vertex). The fourth option matches the definition of a prism: two parallel, identical bases connected by rectangles.

Answer:

A prism is a polyhedron with two parallel faces that are identical copies of each other, called bases, connected by rectangles.
