Video 3: Geometry
Austin test-drives his partially completed car (it has no body yet) and it doesn't go very straight.  he can't figure out why. Bridget has been studying shapes in school and notices the triangles on the plans and the one s on the car made by the axles aren't the same. Austin says, "Close enough!" They argue about the importance of Bridget's observation and go to Alex to settle the argument. He's working on his old car and shows them the tires, one of which has a wear pattern that suggests it's out of alignment. Their discussion revolves around what that would mean. Finally Austin has an "aha!" moment and runs off to fix his racer.
