Determine the angle of rotation so a figure maps onto itself
Jun 25­11:09 AM
If this figure has rotational symmetry, what is the angle of rotation that maps the figure onto itself?
Jun 25­11:09 AM
If this figure has rotational symmetry, list all angles of rotation that map the figure onto itself.
Would 180° work?
Does anything else?
