This article describes a unit of work that was designed for a Year 9 class of mixed ability and which involved the definition and measurement of angles, as well as the practical application of angle properties--such as complimentary angles and the relationships in a transversal. The unit considered the numeracy skills required to interpret a safety warning on a ride-on lawnmower--an application which would make even the most cynical and disaffected teenager reluctant to ask, "Why are we doing this?" Such a practical application of mathematical understanding can provide an important illustration for students of how they might use such knowledge in daily life. (Contains 6 figures.)
