# Hinge Dissection: Gnomon to a Square

Here is a simple dissection that turns a gnomon inside out to form a square. This is a hinged dissection so the pieces stay connected as they swing from one shape to the other.

## Steps

- Cut out the piece from the pattern.

- Cut the interior lines of the piece. Note that there is only one place where you cut through the tabs.

- Fold the tabs up perpendicular to the rest of the model.

- Turn the gnomon inside out to form the square.
