Annotated Euclidean Geometry, Books One – Six (TEXTBOOK)

Please view / download a PDF sample of this book.

In this textbook, student enjoys the first six (of the thirteen) books of Euclid’s classic geometry book called The Elements, all carefully annotated by Christ the King Books.

Euclid (known as the “father of geometry”) lived some 2,500 years ago. It is hard to say enough positive and admiring remarks about Euclidean geometry, and what it does for the young (or older!) mind. The plain truth is that there is simply no book we know of – whether in mathematics, logic, or any subject – which is more fundamental or effective at forming the mind in the habit of careful and logical reasoning. Euclidean geometry is the best example a true science in existence. No other science does a better job of presenting a system of careful proofs built upon certainly-knowable first principles. (On earth, we do not even truly know the first principles of sacred theology, as St. Thomas Aquinas explains).

Few parents realize this, but The Elements was the standard upper school geometry text in the United States until the early 1900’s. There was good reason for this! The mind of the student greatly matures and expands by working through this classic. Until that time, education had been considered first and foremost for the sake itself – truth is simply beautiful, and it is human to form the mind with good intellectual habits. Afterwards however, an education was considered primarily for making money, solving problems, and making products, etc. This is tragic. We all want our children to succeed in the world and have good jobs after graduation. But experience shows that the temporal needs are taken care of naturally if the mind is first formed and sharpened.

We beg you not to miss the opportunity to expose your children to a true classic in math and logic. Studying even the first six of these classic thirteen books will make an astounding difference in your child’s thinking.

Recommended for older high school students: 10^th – 12^th grade, although very mature and diligent 9^th graders can do it, as shown in the associated videos offered separately. Excellent for adults, too! See also our video series to accompany this book.
