. How many lines of symmetry does a square have
The number of lines of symmetry in a regular polygon is equal to the number of sides of that polygon.
A square has 4 sides.
Thus use this information along with the concept explained previously to get the answer.
A regular square has 4 sides and 4 lines of symmetry.
The number of lines of symmetry in a regular polygon is equal to the number of sides.
There are 4 lines of symmetry in a regular square.
Two of them go from a vertex to the opposite vertex and two of them go from midpoint of side to the midpoint of the opposite side.
Consider a regular square ABCD as shown in figure the line of symmetry is also shown as 1, 2, 3, 4 which folds the square into two equal halves.
So, the regular square has 4 sides so the regular square has 4 lines of symmetry which folds the square into two equal halves.
Hence option(D) is the correct option i.e. 4.
