1. Find the number of lines of symmetry for each of the following shapes : Solutions:

(a) For the given figure there are 4 lines of symmetry.

(b) For the given figure there are 4 lines of symmetry.

(c) For the given figure there are 4 lines of symmetry.

(d) For the given figure there is only 1 line of symmetry.

(e) For the given figure there are 6 lines of symmetry.

(f) For the given figure there are 6 lines of symmetry.

(g) For the given figure there is no line of symmetry.

(h) For the given figure there is no line of symmetry.

Now we may observe the lines of symmetry in the above figures as follows 2. Copy the triangle in each of the following figures on squared paper. In each case, draw the line(s) of symmetry, if any and identify the type of triangle. (Some of you may like to trace the figures and try paper-folding first!) Solutions:

(a) The given triangle is an isosceles triangle. Here it will be only 1 line of symmetry. (b) The given triangle is an isosceles triangle. Here it will be only 1 line of symmetry. (c) The given triangle is a right angled triangle. Here it will be only 1 line of symmetry. (d) The given triangle is a scalene triangle. Here it will be no line of symmetry.

3. Complete the following table. Solutions:

The given table is completed as follows: In case of circles we find infinite lines. Here some lines of symmetry are drawn. Similarly, we can draw more symmetric lines for the circle.

4. Can you draw a triangle which has
