Excellent teaching, you made this so easy to understand. I have been looking for a video like this on You Tube and yours is the best one I have seen. I do have one question, when calling north it can be zero or 360, east is always 90, and south can also be called zero or 180, but west is a mystery to me. It seems to just have one option which is 270. However, I have seen it written in a deed placed as 000 degrees west which makes no sense to me. So how should west be called in most cases?
