Question

Which of the following three dimensional objects has rotational symmetry about a line

Answer 1

equilateral triangle, kite, regular pentagon, regular hexagon

a hexagon has rotational symmetry. Furthermore, the angle of rotation is 60° and since there are six copies of 60° in 360° (360 ÷ 60 = 6), we have that the order of rotation of a regular hexagon is six.

let me know if none of these r choices on ur test i will give u more examples :)
