parallelogram, because if the two bases are congruent and parallel then the sides will also have to be parallel, so it is a parallelogram
a cylinder!
Triangle
A prism has two congruent parallel bases.
When a base is congruent it is the same shape and size, and parallel is when they will never touch. Therefore, on a square the top and bottom are congruent parallel bases. Some other examples are: Cylinders, rectangular prisms, and of course parallelograms.
Both a cylinder and a prism can have parallel and congruent bases.
Most things do not have two congruent parallel bases. I do not, by desk does not, my lap top does not, etc etc.
A 3D shape with two parallel and congruent faces is called a prism. In a prism, the two parallel faces are referred to as bases, and the sides connecting these bases are parallelograms. Common examples of prisms include rectangular prisms and triangular prisms. The overall shape retains a consistent cross-section along its height.
An upright pentagonal prism has two congruent parallel bases and 15 edges.
A prism has two parallel and congruent bases in the shape of polygons. Example - a cereal box (is rectangular prism). The top and bottom are rectangles(a polygon). They are the same size and shape (congruent) and also parallel. A cube (think of six sided dice) is a special rectangular prism. Imagine a a box where the top and bottom are triangles (of the shape size and shape). This is called a triangular prism.
A cylinder has two congruent parallel discs for its bases. These bases are identical circles located at each end of the cylinder, and the sides connect these bases perpendicularly. This geometric shape is commonly found in various applications, such as in pipes and storage containers.
