Let P = ( − − 1, 0), Q = (0, 0) and R = (3, 3 
) be three points. Then the equation of the bisector of the angle PQR is
A
x + y = 0
B
x + 
y = 0
y = 0
C
x + y = 0
D
x + 
y = 0
y = 0
Text Solution
Verified by ExpertsThe correct answer is:
B
tan θ θ = 
⇒ ⇒ θ θ = 60 0
⇒ ⇒ ∠ ∠ PQR = 120 0
⇒ ⇒ bisector will have slope tan 120 0
⇒ ⇒ equation of bisector is
x + y = 0.
