Triangle - Rotational Symmetry

ROTATIONAL SYMMETRY
Rotate the polygon by moving the [b]RED X[/b] around the circle. Note each time the rotating polygon rotates "onto" the original shaded polygon.
Number of Rotational Symmetries
How many times does a [b]REGULAR TRIANGLE[/b] rotate onto itself until it is back to the beginning? Include the rotation 360°.
List Rotational Symmetries
Choose the list that includes all Rotational Symmetries for a [b]REGULAR TRIANGLE[/b]
