To see this more clearly, take a piece of paper that is rectangular in shape and fold in half from top to bottom. When you unfold you will see the crease through the middle of the paper and notice that both halves are symmetrical, meaning mirror images of each other, and identical in size and shape. Now, fold the paper in half again from left to right. When you unfold you will see a second crease, forming a cross over the first. The two creases represent the two lines of symmetry.
Note: Technically a square is also a rectangle, but has 4 lines of symmetry since you can also divide a square into symmetrical shapes from the corners, or on the diagonal.

They both have the same amount of lines of symmetry. * * * * * Not true. A square has four lines of symmetry, a rectangle only two.
Only two - parallel to and halfway between the sides. The diagonals are not lines of symmetry.
A quadrilateral with 4 right angles can only be a rectangle or a square. A rectangle has only two lines of symmetry - the lines joining the midpoints of its opposite sides. So the answer cannot be a rectangle. A square has the same lines of symmetry as a rectangle, plus the two diagonals - 4 lines in all.

Four - Two reflective, and two rotational about the diagonals.
