# (i) How are prisms and cylinders alike?

(ii) How are pyramids and cones alike?

**Solution:**

A prism is a polyhedron whose base and top are congruent polygons and whose other faces, i.e., lateral faces are flat in shape. A pyramid is a polyhedron whose base is a polygon (of any number of sides) and whose lateral faces are triangles with a common vertex.

(i) A prism and a cylinder are alike because it can be considered as a circular prism having a curved face. Thus the opposite faces are congruent and parallel.

(ii) A pyramid and a cone are alike because it can be considered as a circular pyramid having a vertex at the top with a lateral curved face.
