Euclid's Elements Book 7 - Proposition 37

I have started converting the presentations into PDFs (while improving? and proofreading them first). You can find the PDFs here: https://drive.google.com/drive/u/1/folders/1w9wynwkfEjiNlNMFgeGbRrVlBtVSvSWw NB: I will be uploading the PDFs slowly (at the moment (June 2019) only books 1-2, but the 3-7 coming very soon.
