Triangle - Rotational Symmetry
ROTATIONAL SYMMETRY
Rotate the polygon by moving the RED X around the circle. Note each time the rotating polygon rotates "onto" the original shaded polygon.
Number of Rotational Symmetries
How many times does a REGULAR TRIANGLE rotate onto itself until it is back to the beginning? Include the rotation 360°.
