If you let , plug into the given equations, you will find out that the straight lines are and . They are perpendicular to each other, hence the angle of intersection is 90.
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.
