The 13 books of Euclid's Elements are generally referred to by their book number.
The main subject matter of each book:
Book 1 contains the basic properties of geometry: the Pythagorean theorem, equality of angles and areas, parallelism, the sum of the angles in a triangle, and the three cases in which triangles are "equal" (have the same area).
Book 2 is commonly called the "book of geometrical algebra," because the material it contains may easily be interpreted in terms of algebra.
Book 3 deals with circles and their properties: inscribed angles, tangents, and the power of a point.
Book 4 is concerned with inscribing and circumscribing triangles and regular polygons.
Book 5 is a treatise on proportions of magnitudes.
Book 6 applies proportions to geometry: Thales' theorem, similar figures.
Book 7 deals strictly with elementary number theory: divisibility, prime numbers, greatest common divisor, least common multiple.
Book 8 deals with proportions in number theory and geometric sequences.
Book 9 applies the results of the preceding two books: the infinitude of prime numbers, the sum of a geometric series, perfect numbers.
Book 10 attempts to classify incommensurable (in modern language, irrational) magnitudes by using the method of exhaustion, a precursor to integration.
Book 11 generalizes the results of Books 1-6 to space: perpendicularity, parallelism, volumes of parallelepipeds.
Book 12 calculates areas and volumes by using the method of exhaustion: cones, pyramids, cylinders, and the sphere.
Book 13 generalizes Book 4 to space: golden section, the five regular (or Platonic) solids inscribed in a sphere.
