When you're looking at something from the side, you might describe it as a side-view. However, there are many different synonyms you can use to describe this perspective. Some options might include a profile view, a lateral view, or a flank view. You could also describe it as a perpendicular view or even a horizon view, depending on the context. If you're looking at something from an angle, you might use terms like an oblique view or a slanting view. Ultimately, the best synonym for side-view will depend on the exact perspective you're trying to describe and the context in which it's being used.
