How do you draw angles using an protractor?
Angles are created using a special tool called a protractor. Protractors measure the number of degrees in an angle.
Helpful hints: Right angles are exactly 90 degrees, straight angles exactly 180 degrees. Acute angles are less than 90 degrees and obtuse angles are between 90-180 degrees. Any angle bigger than 180 degrees is called a reflex angle.
