        I’ve tried to demonstrate it here. You end up with straight lines because it’s always a middle point so it doesn’t curve one way or another between the two points.

        If the circles had a set radius then you’d have empty space and more circley-looking spots. But since they basically expand until there’s a middle point you’ll have these straight lines.

        Draw it, then consider where the exact middle point would be. Now do the whole line between them. I think that’s the best way to figure it out.
