Induction: Geometry Proof (Angle Sum of a Polygon)

[@zacpeters4118]

Thanks, Eddie, I've been having a hard time finding good explanations of induction. Your explanations are exceptionally clear.

Hey Eddie. Thanks a bunch for your videos. Super enthusiastic and interesting. One question though: in the first step, did you assume your prior knowledge of the sum of interior angles of a triangle being 180 degrees? Are we allowed to do that?

[@kartikaybhardwaj4670]

it comes from the first test case that we tested. 3 sided polygon angle sum = 180 which is triangle. it was the test case that we used rather than making any prior assumption.

basically, yes

@@kartikaybhardwaj4670 When we tested the first case, we had to know before hand that sum of interior angles of a triangle is 180 in order to say that it is true so you actually need the prior knowledge.

If we weren't allowed, why would he do it?
