(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

verify that R, the reals, quotiented by the equivalence relation x~x+1 is S^1

2. Relevant equations

3. The attempt at a solution

All i can think of is to draw a unit square and identify sides like the torus, but this would be using IxI, a subset of R^2, and gives a cylinder at best... Obviously I am missing the point, so any help would be great.
