I put a dot anywhere on the paper. After that I drew two 1 inch lines to form a right angle from the dot. Then I draw line to connect the two 1 inch lines. When I did this it formed a right triangle.
After I created my first right triangle I put the dot that is located in the bottom middle of the protracted on top of my triangle highest peek,
After I made my make at 90 degrees. I the used the ruler at the bottom of the protractor to draw another inch line aiming at the 90 degree mark. This line stemmed from the top of the hypotenuse on the original triangle I drew.
