Secant line Secant line In geometry, a secant of a curve is a line that intersects the curve in at least two (distinct) points. The word "secant" comes from the Latin word "secare", meaning "to cut". In the case of a circle, a secant will intersect the circle in exactly two points and a chord is the line segment determined by these two points, that is the interval on a secant whose endpoints are these points. A straight line can intersect a circle in two, one or zero points. A line intersecting in two points is called a "secant line", in one
Fife Circle Line Fife Circle Line The Fife Circle is the local rail service north from Edinburgh. It links towns of south Fife and the coastal towns along the Firth of Forth before heading to Edinburgh. Operationally, the service is not strictly a circle route, but, rather, a point to point service that reverses at the Edinburgh end, and has a large bi-directional balloon loop at the Fife end. The service includes the Edinburgh-Dunfermline stretch of the East Coast Main Line, which includes the world-famous Forth Bridge. On the Fife side, while this line hugs the coast, the circle is formed by a
