Question

what is the smallest degree measure for a regular nonagon to rotate onto itself? (1 point)
40°
30°
80°
60°

Explanation:

Step1: Determine number of sides

A regular nonagon has 9 sides, so \( n = 9 \).

Step2: Calculate rotation angle

Smallest rotation angle = \( \frac{360^\circ}{n} = \frac{360^\circ}{9} = 40^\circ \).

Answer:

A. 40°
