The unit problem was to find a formula that expressed "s" (the length of a shadow) in terms of the variables L, D, and H (the unit problem is expressed in the diagram below).

Some of the components that we had to learn in order to solve the unit problem were similarity, congruency, right triangles, trigonometry, logical reasoning, and proofs. We began by examining shadows and the variables that affected the lengths of them; in homework 2 my group took the height of the light source and varied it to see if it made a change in the length of the shadow. When we did similarity we began by drawing simple objects and shrinking them or enlarging them to show the similarity. In homeworks six through thirteen we found how angles must be congruent and sides must be proportional in order for two triangles to be similar to each other. Proportions were another main idea in this unit because they gave us an understanding on how two ratios must relate to each other.
