Is the rule of rotational symmetry can be said correct for a triangle?
Order of rotational symmetry for a scalene triangle is ___.
___ triangle is a figure that has a line of symmetry but does not have rotational symmetry.
Draw, wherever possible, a rough sketch of
(i) a triangle with both line and rotational symmetries of order more than 1.
(ii) a triangle with only line symmetry and no rotational symmetry of order more than 1.
(iii) a quadrilateral with a rotational symmetry of order more than 1 but not a line symmetry.
(iv) a quadrilateral with line symmetry but not a rotational symmetry of order more than 1.
