Concurrent lines

Consider the following statements I.Number of circles touching the given three non- concurrent lines is 4. II.Number of circles passing through (1,2),(4,8) and (0,0) is one. Which of the above statement(s) is/are correct?

Statement - 1 : If non-zero numbers a , b , c are in H.P. , then the equation (x)/(a) + (y)/(b) = (1)/(c) represents a family of concurrent lines . Statement- 2 : A linear equation px + qy = 1 in x , y represents a family of straight lines passing through a fixed point iff there is a linear relation between p and q .

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

The least positive value of t so that the lines x=t+a,y+16=0 and y=ax are concurrent is

Lines p,q and r are concurrent.Also lines p, s and t are concurrent.Is always true that the lines q,r and s will be concurrent? Is it always true for lines q,r and t?

Lines p,q and r are concurrent.Also,lines p,r and s are concurrent.Draw a figure and state whether lines p,q,r and s are concurrent or not.
