![]() On the equivalence of sets of equal measures by countable decomposition. ![]() Use these semicircles, a semicircle semi means half So use these half circles to make a circle so if you take two halfs of a circle and if you put them together just right You're going to make a circle So how do we do that? Well this first choice right over here, these are no longer the semicircles These are each a third of a circle So we're not gonna, and this isn't even complete the entire circle so that didn't make a circle This one, they took the two semicircles but they didn't make them so that their outsidesĬompletely line up with each other.
