Question

complete the following sentence. the figure below has rotational symmetry. ° is the smallest possible rotation that results in the figure being mapped onto itself. answer attempt 1 out of 2 you must answer all questions above in order to submit.

Explanation:

Step1: Count the number of congruent parts

The figure has 18 congruent parts.

Step2: Use the formula for rotational symmetry

The formula for the angle of rotational symmetry is \(\frac{360^{\circ}}{n}\), where \(n\) is the number of congruent parts. Here \(n = 18\).

$$ \frac{360^{\circ}}{18}=20^{\circ} $$

Answer:

\(20\)
