Which statements are true regarding the regular dodecagon? Check all that apply.

A regular dodecagon has 12 equal positions around a full turn, so its smallest rotation that maps it onto itself is 360° ÷ 12 = 30°. Its rotational symmetries are multiples of 30°, which includes 180° (6 × 30°), but not 135°. The order is 12, not 10. Therefore, the true statements are that the smallest angle is 30°, it has rotational symmetry of 180°, and its symmetry angles are multiples of 30°.
