Part I Complete triangle CDE that is similar to ABC. Where does D need to be to create a similar triangle? Label vertex D and mark the angles that have the same measure. (2 points)
Part II Assign a variable to name the length of BC and label it on your figure. To identify the lengths of AB, CD, and DE, use the dimensions of the pool table. Some lengths will include a variable. (4 points: 1 point for each label)
Part III Use your similar triangles to set up a proportion. Solve this proportion for the unknown variable, the length of BC. (5 points: 2 points for the proportion, 3 points for the work)
