State, whether true or false:

(i) The letter B has one line of symmetry.

(ii) The letter F has no line of symmetry.

(iii) The letter O has only two lines of symmetry.

(iv) The figure

has no line of symmetry.

(v) The letter N has one line of symmetry.

(vi) The figure

has one line of symmetry.

(vii) The letter D has only one line of symmetry.

(viii) A scalene triangle has three lines of symmetry.

(i) True

Reason:

The letter B has one vertical line of symmetry that divides it into two identical halves.

(ii) True

Reason:

The letter F has no line of symmetry, as there is no way to divide it into two identical halves, either vertically or horizontally.

(iii) False

Reason:

The letter O has an infinite number of lines of symmetry, as any line passing through its center divides it into two identical halves.

(iv) False

Reason:

There are two lines of symmetry that can divide the above figure into two equal halves.

(v) False

Reason:

The letter N has no lines of symmetry. There is no way to divide it into two identical halves along any line, either vertically or horizontally.

(vi) True

Reason:

There is only one line of symmetry that can divide the above figure into two equal halves.

(vii) True

Reason:

The letter D has one line of symmetry that divides it into two identical halves.

(viii) False

Reason:

A scalene triangle has no lines of symmetry, as all its sides and angles are of different lengths.
