Questions
If two lines and are the angular bisectors of two lines then the relation between is
a
4l−3m=0
b
3l−4m=0
c
2l−3m=0
d
l−m=0
detailed solution
Correct option is A
The angle between angular bisectors of any two intersecting lines is 90∘ If two lines a1x+b1y+c1=0 and a2x+b2y+c2=0 are perpendicular then a1a2−b1b2=0 Here 4x+3y+5=0 and bx+my+4=0 are perpendicular. Therefore, 4l−3m=0Talk to our academic expert!
