Question
determine the number of degrees you can rotate the isosceles triangle to carry it onto itself, if possible.
a rotation of will carry the isosceles triangle onto itself. put your answers in order from least to greatest
#45° #60° #72° #90° #120° #135° #144° #180° #216° #225° #240°
#270° #288° #300° #315° #no rotational symmetry
Step1: Concepto de simetría rotacional
La simetría rotacional de una figura es el ángulo de rotación \( \theta \) (donde \( 0^{\circ}<\theta\leq360^{\circ} \)) tal que al rotar la figura en \( \theta \), la figura se superpone a sí misma. Un triángulo isósceles (que no es equilátero) no tiene simetría rotacional (excepto la rotación de \( 360^{\circ} \), pero \( 360^{\circ} \) no está en la lista).
