Six different shapes are cut from a square as shown on the left. Which option(s) is/are made using only the cut pieces? Pieces can be rotated and not all pieces need to be used.
Show Hint
For cut-and-assemble problems:
\begin{itemize}
\item Compare angles and edge lengths closely,
\item Rotation is allowed but reflection is not,
\item Try matching the largest pieces first.
\end{itemize}
Step 1: Observe the square on the left and identify the six distinct pieces formed by the cuts. Note their shapes, angles, and relative side lengths.
\bigskip
Step 2: Remember that:
\begin{itemize}
\item Pieces may be rotated,
\item Pieces cannot be resized or reflected,
\item Not all pieces must be used.
\end{itemize}
\bigskip
Step 3: Examine each Carefully and check whether the shown figure can be assembled exactly using only the given cut pieces:
\begin{itemize}
\item A: Requires a shape that does not match any available piece — invalid.
\item B: Can be perfectly assembled using a subset of the given pieces — valid.
\item C: Contains angular mismatches and incompatible edges — invalid.
\item Option D: Matches the geometry of the available pieces when rotated appropriately — valid.
\end{itemize}

Final Answer:
\[
\boxed{\text{B, D}}
\]
