Find the number of lines of symmetry for each of the following shapes.

(a)		(b)		(c)
(d)		(e)		(f)
(g)		(h)		(i)

TIPS If we fold a picture about a line such that the one half fits exactly over the other half, then this line is called the line of symmetry.

Answer:

                (a) Given figure is Here, \[{{l}_{1}},{{l}_{2}},{{l}_{3}}\]and \[{{l}_{4}}\]are four lines of symmetry. (b) Given figure is Here,\[{{l}_{1}},{{l}_{2}},{{l}_{3}}\] and \[{{l}_{4}}\] are four lines of symmetry. (c) Given figure is Here, \[{{l}_{1}},{{l}_{2}},{{l}_{3}}\] and \[{{l}_{4}}\] are four lines of symmetry. (d) Given figure is                                     Here, \[{{l}_{1}}\]is the only line of symmetry. (e) Given figure is Here, \[{{l}_{1}},{{l}_{2}},{{l}_{3}},{{l}_{4}},{{l}_{5}}\] and \[{{l}_{6}}\] are six lines of symmetry. (f) Given figure is                    Here, \[{{l}_{1}},{{l}_{2}},{{l}_{3}},{{l}_{4}},{{l}_{5}}\]and \[{{l}_{6}}\] are six lines of symmetry. (g) Given figure is No line of symmetry is here. (h) Given figure is No line of symmetry is here. (i) Given figure is Here,\[{{l}_{1}},{{l}_{2}},{{l}_{3}},{{l}_{4}}\] and \[{{l}_{5}}\]are five lines of symmetry.
