(i)An equilateral triangle has both line and rotational symmetries of order more than 1.

(ii) An isosceles triangle has only one line of symmetry and no rotational symmetry of order more than 1.

(iii) It is not possible because order of rotational symmetry is more than 1 of a figure, most acertain the line of symmetry.

(iv) A trapezium which has equal non-parallel sides, a quadrilateral with line symmetry but not a rotational symmetry of order more than 1.
