And in like manner two lines or points may actually touch one another and
coincide . But besides this , there is an imaginary coincidence frequently
appealed to by geometers ; which is , when it can be shown that coincidence

And because B is equal to C , in like manner would B and C. But because A and
B would each coincide with C ; if the boundaries of both could be applied to those
of C at once , A and B would coincide with one another ; wherefore A and + 1.
