Answer:
Square
Hexagon
See below for explanation
Step-by-step explanation:
The question is incomplete without the figure being referred to in the question.
We can tell from the question, we are to determine the shape that would be obtained when a pyramid is cut with a plane parallel to its base.
Since we were not told the type of pyramid, let's consider the shape that would be derived from the following pyramid when a plane is cut parallel to its base:
a) square pyramid:
When a plane cuts through a square pyramid parallel to its base, the shape (cross section) parallel to the base will be a square.
b) hexagonal pyramid:
When a plane cuts through a hexagonal pyramid parallel to its base, the shape (cross sections) parallel to the base will be a hexagon.
