2. What is the definition of a prism? * .
(A) A prism is a polyhedron with two parallel faces that are identical copies of each other, called bases, connected by rectangles.
(B) A prism is a polygon with 4 straight sides and four vertices.
(C) 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.
(D) A prism is a polygon with three straight sides and three vertices.
A
Better review the topic some more.
Also, it wouldn't hurt to check out the other choices, so you'll be able to recognize the other shapes when needed.
The correct answer is (A) A prism is a polyhedron with two parallel faces that are identical copies of each other, called bases, connected by rectangles.
The correct definition of a prism is (A) A prism is a polyhedron with two parallel faces that are identical copies of each other, called bases, connected by rectangles.
To understand the definition, we need to break it down.
First, a prism is a polyhedron. A polyhedron is a solid shape that has flat, polygonal faces, straight edges, and vertices (corners).
Next, a prism has two parallel faces called bases. These bases are identical copies of each other, meaning they have the same shape and size. For example, if the base is a square, both bases will be squares.
Finally, the bases are connected by rectangles. These rectangles are called lateral faces. The lateral faces are perpendicular to the bases and connect them together. The lateral faces are also congruent (meaning they have the same shape and size).
By understanding this definition, we can determine that option (A) is correct, as it accurately describes a prism.
