Question
the figure below rotational symmetry. has does not have is the smallest possible rotation that results in the figure being mapped onto itself. try reset
Step1: Comprender la simetría rotacional
La simetría rotacional se refiere a la propiedad de una figura de coincidir consigo misma después de una rotación menor que \(360^{\circ}\).
Step2: Contar el número de secciones congruentes
Observando la figura, se pueden contar \(18\) secciones congruentes.
Step3: Calcular el ángulo de rotación
El ángulo de rotación mínimo se calcula dividiendo \(360^{\circ}\) entre el número de secciones congruentes. Entonces, \(\frac{360^{\circ}}{18} = 20^{\circ}\).
