How are pyramids and cones different than prisms and cylinders?

A prism is a polyhedron which has two congruent bases and a pyramid has only one base

A cylinder has two circular bases  such that it's sides are curved not flat.

A cone has only one circular base with one vertex.

Step-by-step explanation:

A prism  and a prism are three dimensional figures with sides and faces as polygons.

A prism is a polyhedron which has two congruent bases and a pyramid has only one base.

The base is not of the form of circle or oval.The sides and bases are always polygons.

The base can be square , triangle , rectangle etc.

Cone and cylinder are also three dimensional figures with some differences.

A cylinder has two circular bases  such that it's sides are curved not flat.

A cone has only one circular base with one vertex.

step-by-step explanation:

for exempl this   system of equations   y = x - 3

                                                                y = 2x - 5

look   the line : y = x -3     ( red)

                            the line : y = 2x -5 ( bleus)
