PLEASE PLEASE PLEASE HELP ASAPP Question: In the movie Lincoln Lincoln says "Euclid's first common notion is this: Things which are equal to the same things are equal to each other. That's a rule of mathematical reasoning and it's true because it works - has done
and always will do. In his book Euclid says this is self-evident. You see there it is even in that 2000 year old book of mechanical law it is the self-evident truth that things which are equal to the same things are equal to each other."
Explain how this common notion is an example of a postulate or a theorem
