Description:

This drawing shows a flashlight lying on its side and taped to the top of block. It is shining on a cutting board with a piece of graph paper attached that is being rotated through 0, 10, 20, 30, and 40 degrees. The protractor measurement for the degree of tilt is taken at the point where the cutting board contacts the floor.
