Questions
Let and be three points. Then, the equation of the bisector of the angle is
a
32x+y=0
b
x+3y=0
c
3x+y=0
d
x+32y=0
detailed solution
Correct option is C
The bisector of angle PQR divides PR in. the ratio PQ : QR i.e. 1 : 6. So, the coordinates of the point of division are 1×3+6×−11+6,1×33+6×01+6=−37,337Clearly, required bisector passes through Q (0, 0) and (-3/7, 33/7). So, its equation is y−0=337−0−37−0(x−0)⇒y=−3x⇒3x+y=0.Talk to our academic expert!
