Angles

The tool used to measure degrees is called a protractor. You can make a protractor by printing from a template or folding a square of paper. Use transparent standard size paper 8½ inches x 11 inches into a square (8 ½ x 8 ½ inches).Fold the paper precisely and tightly. You should get 16 angles surrounding the center. Tear or cut off the resulting wedge shape (4-5 inches from vertex.). Use your protractor to measure angles. You may call the unit of measure “wedges” (like degrees).
