In this activity, students will explore the proportional relationships involved in multiple parallel lines being cut by transversals. These relationships are approached through exploration of a sail design problem, where students are to find the lengths of pieces of fabric along the edge of a sail which has a design utilizing parallel lines. An understanding of the "Side-Splitter Theorem" and its corollary will be developed via exploration.
