In this context, a circle is tangent to a line when it just "kisses" the line -- approaches, touches, and then departs on the same side of the line. The place where it touches is the part of the line closest to the circle's center, and the circle's radius at that point meets the line at right angles. In trigonometry, the tangent function tan(theta) is defined as sin(theta)/cos(theta) -- I think there's a way of drawing triangles and circles so the name makes sense with the previous definition. -- Bill -----Original Message----- From: Peter Fogg [mailto:ffive@TPG.COM.AU] Sent: Thursday, May 29, 2003 7:10 PM To: NAVIGATION-L@LISTSERV.WEBKAHUNA.COM Subject: Re: Bisectors and MPP - for 3 sights, equivalent to circle method From: "Noyce, Bill" > ... when I should have said > . is tangent to all three LOP's Can you please explain to me what a tangent is?
