Respuesta :

answer.

•given that is smallest angle of rotational symmetry for a regular polygon is 30

•we have to find the number of side does the regular polygon have

•if we can rotate of figure around a center point be fewer than 360° and the figure appears and change then the figure has the rotation symmetry

Hence,12 number of sides the polygon.

no. of side= 360/ smallest angle at centre=12

I hope it's help
