So, as a little foreword to you, as a tip when writing formal proofs and deducing data, since it's the main goal in Euclidean geometry. Whever we write a proof, we will always... ALWAYS, work with the given information an pre-knowledge of geometry. With that I mean, you only have to relate the given information to draw a conclusion and with the new data, you can go further. To the given information we call "hypothesis" wich, in difference of the verbal definition of "hypothesis", as a mathematical definition it means information that is true. So, going back to Decart who, I quote, said: "To conclude something true, the premises wich it derived from, must also be true". So for that reason, the best way to start off with a proof is to associate the hypothesis, meaning, the informaton we were given. Let's do that: Hypothesis: (1)
