It let's you measure angles on paper.

Take a square piece of paper and a cylinder shaped cup and trace the openingpart of the cup so you have enough space to write in the numbers.This is for when you urgently need it

If the paper is in inches then 11 times 14 = 154 square inches

fold a piece of paper to fit within the angle. remove the paper and overlay on a protractor and read the angle. cem fold a piece of paper to fit within the angle. remove the paper and overlay on a protractor and read the angle. better yet, use the paper form to trace out and build the replacement shelf! cem
