On a squared paper, sketch the following:

(i) A triangle with a horizontal line of symmetry but no vertical line of symmetry.

(ii) A quadrilateral with both horizontal and vertical lines of symmetry.

(iii) A quadrilateral with a horizontal line of symmetry but no vertical line of symmetry.

(iv) A hexagon with exactly two lines of symmetry.

Copy the following figure on a squared paper and complete each figure such that the resultant figure is symmetrical about the dotted line (or lines):

Copy the following figure on a squared paper and complete each figure such that the resultant figure is symmetrical about the dotted line (or lines):

State whether the following statement is true or false. Justify your answer:

"A straight line dividing a figure into two identical parts is necessarily a line of symmetry."
