Example.

What is mentby like cantles you haue heard before. and it is easie to vnderstand, that suche figures are called equall, that be of one bygnesse, so that the one is nother greater nother lesser then the other. And in this kinde of comparison, they must so a∣gree, that if the one be layed on the other, they shall exactly a∣gree in all their boundes, so that nother shall excede other.

[illustration] diagram

Nowe for the ex∣ample of the Theo∣reme, I haue set for∣the diuers varieties of cantles of circles, amongest which the first and seconde are made vpō equall li∣nes, and ar also both equall and like. The third couple ar ioy∣ned in one, and be no¦ther equall, nother like, but expressyng an absurde deformitee, whiche would folowe if this Theoreme wer not true. And so in the fourth couple you maie see, that because they are not e∣quall cantles, therfore can not they be like cantles, for necessa∣rily it goeth together, that all cantles of circles made vpon e∣quall right lines, if they be like, they must be equall also.
