Hello!

I need help with the following question:

Find the point of intersection and the angle of intersection of the straight lines

|z - 1 - j| = |z - 3 + j|

|z - 1 + j| = |z - 3 - j|

I have already found the point of intersection to be z = 2, i.e x=2,y=0. But I don't know how to find the angle of intersection.

All help is much appreciated. Thanks.
