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
