**Ex 14.2 Class 7 Maths Question 1.**

Which of the following figures have
rotational symmetry of order more than 1?**Solution:**

The figures (a), (b), (d), (e) and (f) have rotational symmetry of order more than 1.

**Ex 14.2 Class 7 Maths Question 2.**

Give
the order of rotational symmetry for each figure:

**Solution:**

(a) Let us mark a point S on one end of the
given figure. By rotating the figure 180°, S comes at other end and then again
by rotating the figure 180°, it comes at its original position.

(b) Let us mark a point S on one end of the given figure. By rotating the figure 180°, S comes at other end and then again by rotating the figure 180°, S comes at its original position.

(c) Let us mark any vertex of the given figure as P. It takes three rotations of 120° to come back to its original position.

∴ Order of rotational symmetry = 360°/120° = 3

(d) Order of rotational symmetry = 360°/90° = 4

(e)
Order of rotational symmetry = 360°/90° = 4

(f)
The given figure is a regular pentagon which can take one rotation of 72° to
obtain its original position.

∴ Order of rotational symmetry = 360°/72° = 5

(g)
The given figure requires six rotations of 60° to obtain its original position.

∴ Order of rotational symmetry = 360°/60° = 6

(h)
The given figure requires three rotations of 120° to obtain its original
position.

∴ Order of rotational symmetry = 360°/120° = 3
