Which three-dimensional shapes do not have identical cross sections when cut by planes that are parallel to the base? select all that apply.

cone

rectangular pyramid

cylinder

triangular prism

Answer with explanation:

When cut by a plane, which is parallel to base,the following three dimensional shapes have identical two parts.

1. Cone=Cone +Frustum

2.Rectangular Pyramid= Doesn't have two identical parts

3. Cylinder= Two cylinders

4. Triangular Prism=the two parts are identical,if symmetrical it means cut from between.

So, Option 1: Cone

and Option 2: Rectangular pyramid

are the two shapes which do not have identical parts when cut by a plane parallel to it's base.
