Many products have logos so people can easily
identify them. If you turn the first aid logo below 180˚,
will the logo look the same as the original figure?
A figure has rotational symmetry if it can be rotated
or turned less than 360˚ about its center so that the
figure looks exactly as it does in its original position.
Copy the outline of the first aid logo onto a piece of tracing
paper. Label one vertex A

Place the tracing paper over the outline in Step 1. Put your
pencil point at the center of the figure to hold the tracing
paper in place. Turn the tracing paper clockwise from its
original position until the two figures match. Draw and label
the new figure in the space provided.

Many products have logos so people can easily identify them. If you
turn the first aid logo below 180˚, will the logo look the same as the
original figure?
Continue turning the tracing paper until the logo is back to its
original position. Does the figure have rotational symmetry?
