<h3>answer.</h3>
•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
<h3>Hence,12 number of sides the polygon.</h3>
no. of side= 360/ smallest angle at centre=12
