 Division makes it hard to connect similarity to quantitative differences in the ways one might expect. Consider three triangles A, B, C, where A is equilateral with side length 1m; B is isosceles with side lengths 1m, 1m, 1.01m; and C is isosceles with side lengths 1m, 1m, 1.1m. The paradigms we began with (and the simplicity-of-definition idea, and the connections to mental and linguistic content discussed  §4.7  below) suggest that for most values of \(x\) other than 1, being isosceles with one side \(x\) times as long as the other two is much less natural than being equilateral. Given this, it looks like A and B, being divided by being equilateral, may be counted by Division as more dissimilar than triangles B and C are. This contrasts with a more familiar conception of similarity in this domain, on which the degree of dissimilarity between a 1,1,1 triangle and a 1,1,\(x\) triangle approaches 0 as \(x\) approaches 1.
