Angles measure the amount of turn, or change of direction.
Angles are measured in degrees. A number that is a degree has a small º immediately after the number: 153º means 153 degrees. There are 360º in a complete turn. Half a turn is 180º, and a quarter turn is 90º.
In geometry, angles are seen when two lines join at a point.
Angles have names, depending on the amount of turn in the angle.
