I hear degrees all the time. What are degrees when we are talking about angles?
Degrees are a unit of measurement, like inches or pounds.
Šmykľavka: 2
Degrees measure rotation or turn of an angle in reference to a full circle.

EXAMPLE
A sailor looks straight ahead through a spyglass at another ship. There is no turn, so he is looking at an angle of 0 degrees.

In a full circle, there are 360 degrees. Each degree is 1/360 of a full circle.
Šmykľavka: 6
Some think that 360 was chosen for the number of degrees in a circle because it is close to the number of days in a year.
Šmykľavka: 7
The factors of 360 are 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 18, 20, 24, 30, 36, 40, 45, 60, 72, 90, 120, 180, and 360
360 also has many factors, so a circle can be divided into equal parts easily.
