A full turn around a point equals 360º. If a full turn equals 360º, then the sum of the angles around a point must also be 360º. When you calculate angles around a point, you can use this fact to find ...
An angle is a way of describing the space between 2 lines that begin at the same point. An angle is a measure of how much you have to turn one of the lines so that it perfectly overlaps with the other ...
