Rh 6. Repeat the above process and obtain the edges CD and DA. It is evident by superposition that the angles at A, B, C, D, are right angles, equal to one another, and that the sides BC, CD are respectively

equal to DA, AB. This piece of paper (Fig. 3) is similar in shape to the page.

7. It can be made equal in size to the page by taking a larger piece of paper and measuring off AB and BC equal to the sides of the latter.
