Therefore when soeuer you do see any formes of lynes to touche at one notable pricke, as in this example, then shall you
not call it one croked lyne, but rather twoo lynes: an Angle. in as muche as there is a notable and sensible angle by .A. whiche euermore is made by the meetyng of two seuerall lynes. And likewayes shall you iudge of this figure, whiche is made of two lines, and not of one onely.
So that whan so euer any suche meetyng of lines doth happen, the place of their metyng is called an Angle or corner.
Of angles there be three generall kindes: a sharpe angle, a square angle, and a blunte angle. A righte angle. The square angle, whiche is commonly named a right corner, is made of twoo lynes meetyng together in fourme of a squire, whiche two lines, if they be drawen forth in length, will crosse one an other: as in the examples folowyng you maie see.
Right angles.
A sharpe corner. A sharpe angle is so called, because it is lesser than is a square angle, and the lines that make it, do not open so wide in their departynge as in a square corner, and if thei be drawen crosse, all fower corners will not be equall.
A blunte angle. A blunt or brode corner, is greater then is a square angle, and his lines do parte more in sonder then in a right angle, of whiche all take these examples.
