Geometry notes<3

Okay so for 2.3 the notes the teacher gave us were just examples rather than actual equations and such so I decided not to include it. But basically, if you’re trying to connect or something to everyone else but yourself, so you would instead use the equation n(n-1) with n being the amount people, dots, etc. and if you don’t want to double count like if you’re shaking someone’s hand, so you don’t want to count you shaking theirs and them shaking yours, the equation would morph into n(n-1)/2 !!

Not an expert! Also this is it for chapter 2 <3
