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

What is the angle between the lines x/1 = y/-2 = z/1 and x/4 = y/1 = z/-2 .

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

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

If |z_(1)|=|z_(2)|=|z_(3)|=|z_(4)| , then the points representing z_(1),z_(2),z_(3),z_(4) are :

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

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