Question

if a regular polygon has 19 sides what is the smallest angle of rotation required to get rotational symmetry? if it is a decimal answer round to one decimal place

Explanation:

Step1: Formula for rotational symmetry angle

El ángulo de simetría rotacional más pequeño para un polígono regular con \( n \) lados es \( \frac{360^{\circ}}{n} \). Aquí, \( n = 19 \).

Step2: Cálculo del ángulo

Sustituimos \( n = 19 \) en la fórmula: \( \frac{360}{19}\approx 18.947^{\circ} \).

Step3: Redondeo

Redondeamos \( 18.947^{\circ} \) a un decimal: \( 18.9^{\circ} \).

Answer:

\( 18.9^{\circ} \)
