Answer:
1) Trepzoid
2) Hexagon
Explanation:
A two-dimensional shape is rotated to form the solid object shown in the figure. This two-dimensional shape can be created by rotating a trapzoid about its base. Another two-dimensional shape that can give this shape is a hexagon rotated about a line joining two opposite vertices.
Trapzoid: It is figure whose two sides are parallel and other two sides are non-parallel. Please take a look attachment for trapzoid. If we rotate trapzoid with longer parallel side we will get same 3-D figure as shown in diagram.
hexagon: It is polygon which has six sides. If we rotate hexagon with their opposite vertices. we will get same 3-D figure as shown in diagram. Please see the attach file.
