Name the quadrilaterals which have both line and rotational symmetry of order more than 1.

A square has a line and rotational symmetry of order more than one.

Line Symmetry:

Rotational Symmetry:

If a figure has two or more lines of symmetry, should it have rotational symmetry of order more than 1?

Fill in the blanks:

After rotation by 60^o about a center a figure looks exactly the same as its original position. At what other angles will this happen for the figure?

Can we have a rotational symmetry of order more than 1 whose angle of rotation is

(i) 45^o (ii) 17^o ?
