Degrees instead of inches help

I am having trouble remembering how to do this. I have done it in the past to make the size of the slit bigger or smaller depending on size of material I am using. My problem is when I want to measure the size of the slit it only gives me degrees. How do I resize/measure to be able to change and check slit size? This is one of the dinosaurs I bought.

It’s giving you degrees because the two lines are not parallel. To force them to be parallel you can use a parallel constraint, either to each other or to the construction line you show in the middle.


Thank you that worked.
I resized them an easier way but I cant remember how I did it. I better start keeping notes :woozy_face:
