Definition (keystage 1)

Angle is a measure of turn. A quarter turn is called a right angle.

Definition (keystage 2)

Angle is a measure of turn. Angles are usually measured in degrees (^°).
For example, one whole turn is 360^° and a quarter turn is 90^° or a right angle.

Definition (keystage 4)

When two lines meet each other angles are formed. The size of the angle is the amount of turn needed to take one line and place it on top of the other line. This amount of turn is measured in degrees or radians, or sometimes in grades.
Angle is dimensionless.
