Condition for concurrency of three lines.

Condition OF concurrency || Angle OF triangle made by three lines || Position OF point with respect to line & Examples

Consider the following figure and name: (a) A pair of parallel lines (b) Concurrent lines and point of concurrency ( c ) Three sets of collinear points (d) Six pairs of intersecting lines.

What are concurrent forces ? Obtain a condition for the equilibrium of three concurrent forces

Define the following Concurrent lines.

The lines x+y-1=0,(m-1)x+(m^(2)-7)y-5=0 and (m-2)x+(2m-5)y=0 are concurrent for three values of m concurrent for one value of m concurrent for no value of m parallel for m=3.
