A protractor can be used to measure an angle. An angle is basically part of a circle. A complete circle is 360 degrees. A right-angle is 90 degrees, half a circle is 180 degrees, and so on.

Degrees are used to measure the arc of a circle. A full circle is 360 degrees, and a half circle 180. so 9 degrees would be 1/40th of a complete circle.

How can a circle measure 180 degrees? Circles don't have any angles!

How many degrees does a circle have? 360 degrees.

The idea is that three lines coming out from the center point of a circle (three radii) form three angles -- imagine, for an easy example, the Mercedes-Benz logo. Then the question is: if two of the angles each measure 130 degrees, what does the third angle measure? Well, the first two together measure 260 degrees. So, how many degrees in a circle overall are left, once 260 are taken out? There are 360 degrees in a circle, so the answer is 100.
