Question

The regular nonagon has rotational symmetry of which angle measures? Check all that apply. 40° 45° 120° 240° 260° 320°

Answer 1

Hi!

To find the semmetry between the nonagon just do this:

360 / 9 = 40

The regular nonagon has rotational symmetry of 40 degrees!

Answer 2

central angle of 360° is divided into 9 equal angles each with a measure

360°/9=40°
