If you absolutely needed to measure an angle to find out its degree measure, you would use a protractor.

A protractor is a shape: semi-circle or full circle, that has degrees marked around the edge. Place the marked centre of the protractor on (for example) the corner of two lines forming a right-angle. The bottom line will be zero, while the vertical line will cross the 90 degrees mark of the protractor, so proving that a right-angle is 90 degrees.
