L1:y−x=0 L2:2x+y=0 L3:y+2=0 On solving the equation of line L1 and L2 we get their point of intersection (0,0) i.e., origin O. On solving the equation of line L1 and L3, we get P=(−2,−2). Similarly, we get Q=(−1,−2) We know that bisector of an angle of a triangle, divide the opposite side the triangle in the ratio of the sides including the angle [ Angle Bisector Theorem of a Triangle ] ‌∴‌
