A) concurrent
B) the sides of quadrilateral
C) the sides of a parallelogram
D) the sides of a square
Correct Answer: A
Solution :
Given equations of lines are \[x+2y-3=0\] ...(i) \[2x+3y-4=0\] ...(ii) \[3x+4y-5=0\] ...(iii) and \[4x+5y-6=0\] ...(iv) On solving Eqs. (i) and (ii), we get \[x=-1,\,\,y=2\] From Eq. (iii), \[3(-1)+4(2)-4=0\] \[\Rightarrow \] \[0=0\] From Eq. (iv), \[4(-1)+5(2)-6=0\] \[\Rightarrow \] \[0=0\] Hence, given lines are concurrent.You need to login to perform this action.
