Parallels and Transversals

This lesson is an introductory lesson to the properties of angles created by parallel lines and lines that transverse them. “Make it Fit” introduces the concept of repeating shapes in art (tessellations) and in the growing fuel-conscious economy. The lesson considers the aesthetic appeal of tessellations and the practical need of knowing how things fit together.

Students will explore real-world applications of these ideas and then break down those ideas to better understand the careful consideration of angles which is central to each example. Students will create and test conjectures about the angles and use their results to derive and analyze resulting logical arguments.
