Angle between lines joining `z_1;z_2 and z_3;z_4`

Equation of perpendicular bisector of line joining z1and z2

If z_1 = –3 + 5 i, z_2 = –5 – 3 i and z is a complex number lying on the line segment joining z_1 & z_2 , then arg(z) can be

If z_(1) , z_(2) are two complex numbers such that |(z_(1)-z_(2))/(z_(1)+z_(2))|=1 and iz_(1)=Kz_(2) , where K in R , then the angle between z_(1)-z_(2) and z_(1)+z_(2) is

The angle between the lines => 2x=3y=-z and -6x=y=4z is:

Measure of angle between the lines 2x = 3y=-z and 6x=-y =-4z is

If z1=-3+5 iota and z2=5-3 iota and z is a complex number lying on the line segment joining zl & z2then arg z can be

The angle between lines (x)/(1)=(y)/(2)=(z)/(3) and (x+1)/(2)=(y-3)/(-7)=(z+2)/(4)
