How do you use a right angle to decide how to name another angle?

You use the right angle next to an acute angle perhaps and you see that when a angle is closer together it is an acute angle and if it is spread apart or farther apart from a right angle it is an obtuse angle. If the angle is a straight line and doesn't look bent like a right angle it is a straight angle.
