How does a rectangle have two lines of symmetry? - Answers

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.
