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 (45 inches from vertex.). Use your protractor to measure angles. You may call the unit of measure “wedges” (like degrees).
