Answer 1

A regular nonagon has 9 sides. To determine the smallest degree measure for a regular nonagon to rotate onto itself, we can divide 360° by the number of sides.

So, we calculate:

\[
\frac{360°}{9} = 40°
\]

Therefore, the smallest degree measure for a regular nonagon to rotate onto itself is \(40°\).

The correct answer is:

40°
