I am a third grade teacher...A square has 4 lines of symmetry. 1-Horizontal, 2-Vertical, 3-Diagonal, 4-Diagonal.

It has 2 lines of symmetry because if you go dangle it will change the shape.Yes I know when you go vertical you change the shape.But when you go diagonal you make a triangle and a triangle has 3 angles and a square doesn't.And a rectangle has 4 angles just like a square.

4

Anyone who says it is 4, is correct

The square has two lines of symmetry because if the line goes vertical or horizontal then it would be good.
