There are 9 lines of symmetry and infinite rotational symmetries in first figure,4 lines of symmetry and no rotational symmetries in second figure,6 lines of symmetry and infinite rotational symmetries in third figure,1 line of symmetry and infinite rotational symmetries in fourth figure.
Given four figures.
We are required to find the number of lines of symmetry and rotational symmtries.
Symmetry lines are those lines which act as shape in such a way that both parts are like mirror image.
Rotational symmetry is the property that a shape has when it looks same after some turn.
- There are 9 lines of symmetry and infinite rotational symmetries in first figure.
- There are 4 lines of symmetry and no rotational symmetries in second figure.
- There are 6 lines of symmetry and infinite rotational symmetries in third figure.
- There is 1 line of symmetry and infinite rotational symmetries in fourth figure.
Hence there are 9 lines of symmetry and infinite rotational symmetries in first figure,4 lines of symmetry and no rotational symmetries in second figure,6 lines of symmetry and infinite rotational symmetries in third figure,1 line of symmetry and infinite rotational symmetries in fourth figure.

Answer:
hope this helps.
btw I used synthetic decision method
Squares of Natural numbers from the range of 1 to 20:
1^2 = 1
2^2 = 4
3^2 = 9
4^2 = 16
(whereas 5^2 = 25 which is outside the range).
There are 4 numbers out of 20, so the probability is 4/20*100% = 20%
