It's amazing how doing searches for "geometry textbook", "practical geometry" and "geometry of design" yields so much hippie dippy new age philosophy and conspiracy theories. I am trying to find a hardcover textbook for basic practical geometry, that's more for building and design than math proofs, not uncover the secret message of how to make perpetual motion work, left in the constellations by transdimensional aliens, which was stolen by the Freemasons and hidden in the numerology of the Dewey decimal system.
