What is the difference between the angle of Burgers vector and dislocation line in edge dislocation and screw dislocation?

What is the difference between the angle of Burgers vector and dislocation line in edge dislocation and screw dislocation? Correct Answer 90 degrees

The angle between Burgers vector and dislocation line in edge dislocation is 90 degrees while the angle between burger vector and dislocation line for screw dislocation is 0 degree. To find the difference we have subtract 0 from 90, giving us 90 degrees as our final answer.
