WebBecause we've shown that if x is equal to y, there's no way for l and m to be two different lines and for them not to be parallel. And so we have proven our statement. So now we go in both ways. If lines are parallel, corresponding angles are equal. If corresponding angles are equal, then the lines are parallel.

Therefore there exists an a and b such that f(a) = f(b). Therefore f(x) is not one-to-one. Note: Notice how we used a lot of words instead of math symbols? They are still present, but the main way of communicating with math is through using English. オリゴワンシロップ
