The document contains a table with numbers in the hundreds repeated across rows. Below are equations relating scale factors and ratios. The rest of the document contains notes about shadows, the breakdown of food in the intestine, rotational symmetry, similarities of quadrilaterals, and the definition of order and angle of rotation symmetry.
