About the first one, it cannot be described in a linear separator. But the first circle and the second one are similar things if we choose another way to describe it ---- distance.

So, it's kind of like, we can use a higher dimension to simplify(describe) the problem. And everything can be described in 1-D.

And in mathematics, we have phi = to describe it.
