Parking Lot Activities The activities in this section help students to understand the significance and detail needed to paint lines in a parking lot. To complete these activities, students need access to a parking lot with a common line intersecting several parking spaces. They will also need a protractor large enough to measure the angles created by the intersecting lines. It is preferable, but not essential, to find a parking lot where the lines do not all meet at right angles. This activity is geared to students who are in geometry (usually in 10th or 11th grade) and ready to learn about parallel lines, transversals, and the related angles. Some prior knowledge of basic geometry is required to perform this activity, including (but not limited to) the concepts of intersecting lines, congruent angles, angle measures, naming angles, and the use of protractors. Students should also know the different types of angles that are created by any transversal, including corresponding angles, alternate interior angles, alternate exterior angles, and consecutive interior angles (also called same side interior angles).
