The similarity between a prism and a pyramid is that they are both Polyhedrons.
They both have a base and sides. However, the prism has a second base at the top, which the pyramid does not have.
They are both polyhedra. Therefore the question is based on false premises and so is a waste of time.
they're both shaped like pyramids. And they were both built in ancient times.
they both are three dimensional prism :)
they are both prisms. they both have at least one rectangle
They are both prisms.
Similarity: both of them are solid. Difference: prisms have planes that are parallel to each other whereas pyramids does not have planes which are parallel to each other. XDXD
Both pyramids and prisms are three dimensional. Both of them have polygon faces. Another thing common about pyramids and prisms is that they have a base and faces.
Mayan pyramids are taller while Aztec pyramids were flatter. Both, however were truncated to hold pyramids at the top. Aztecs had more pyramids at the top.
a prism is a prism if it can be cut into even cross sections. that is, if you sliced it in half, both faces would look the same. so, a cube is a prism but not a cone.
