How many lines of symmetry does a square have?
4
The line of symmetry is a line segment that is drawn in between a diagram in order to make the diagram equally divided in two. The line of symmetry divides a picture into two parts so that one forms a mirror image of the other.
Since all the sides of a square are equal, if it is folded across each corner or middle, it overlaps the other half.
A square has 4 lines of symmetry as shown above.
