摘要:
This paper gives a geometric illustration of some of the commonest identities in the algebra of the sum of squares. The method is essentially the construction of squares of the various numbers and their means. These pictures provide us with a visual representation of what the identity says. The method is later extended to represent the identities concerning the sum of products by constructing rectangles.
