How to Measure an Angle with a Protractor?

Angles are measured in degrees.

Step 1. The zero line of the protractor needs to be lined up with one
side of the angle.
You read the set of numbers from your zero line on.

Step 2. To draw an angle of 50 degrees first draw a line segment that
is to be the one side of the angle.

Step 3. Then put the protractor so thats its zero line matches with
your line segment and that the vertex is in place.

Step 4. Now put a mark at the 50 degree point.

Step 5. Then take the protractor off and draw a line through your
mark.
