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.

How do measure an angle with a ruler?
You should use a special device for measuring angles - a protractor. With a ruler, it is much more complicated, but still possible: you can mark two points on the angle, one on each side; measure the distance from the vertext of the angle to those points; measure the distance between the points; then use the Law of Cosines to calculate the angle.
