Somebody please put something in the comments for the title of the next time I do a mastery challenge

This mastery challenge needed me to know how to do geometric tranlations and rotations. I also had to know how to determine the angle of a specific intersection made with multiple lines. I also to know to know the angle of one of the vertecies of a paralellogram while only knowing the lengths of the sides and the angle of one vertex. I learned that the angle of a paralellogram is the same as the angle of the vertex on the opposite side of the given vertex. I can't add the screenshots yet due to an error.
