infinite. Wherfore to define them all seuerally, according to the number of their ••ides, should be very tedious, or rather impossible. Therfore hath Euclide, comprehended thē vnder one name, and vnder one diffinition: calling them many sided figures, as many as haue mo sides then foure: as if they haue fiue sides, sixe, seuen, or mo•• Here note ye, that euery rightlined figure hath as many angles, as it hath sides, & taketh his denomi∣nation aswell of the number of his angles, as of the number of his sides. As a figure cō∣tained vnder three right lines, of the number of his three sides, is called a thre sided fi∣gure ••euen so of the number of his three angles, it is called a triangle. Likewise a figure contained vnder foure right lines, by reason of the number of his sides, is called a foure sided figure: and by reason of the number of his angles, it is called a quadrangled fi∣gure, and so of others.
