Home Geometry Word Cloud Index Euclid's Elements Post a comment       By Antonio Gutierrez

Euclid's Elements is a mathematical and geometric treatise consisting of 13 books written by the Greek mathematician Euclid in Alexandria circa 300 BC. It comprises a collection of definitions, postulates (axioms), propositions (theorems and constructions), and mathematical proofs of the propositions.

Book 2 is commonly called the "book of geometrical algebra," because the most of the propositions are geometric interpretations of algebraic identities, such as a(b + c + ...) = ab + ac + ... or (2a + b)2 + b2 = 2(a2 + (a + b)2).

Word Cloud

Word cloud or tag cloud (or weighted list in visual design) is a visual depiction of user-generated tags, or simply the word content of a site, used typically to describe the content of web sites. Tags are usually single words and are typically listed alphabetically, and the importance of a tag is shown with font size or color. Thus both finding a tag by alphabet and by popularity is possible. The tags are usually hyperlinks that lead to a collection of items that are associated with a tag.
