The number of lines of symmetry in the figure given below is: 0
1 4
2 8
3 6
4 Infinitely many
Explanation:
6 Line of symmetry is the line which divides a figure into two equal halves which are mirror image of each other. So for the given figure, it has six grooves or inside edge through which we can draw three lines of symmetry. The figure also has six outside edge through which we can draw three lines of symmetry. So total six lines of symmetry for the figure is six. The figure is as follows: 1
