Cover art “A student drew this perspective drawing as part of an assignment related to the Mathematics Workplace and Apprenticeship 10 Outcome WA10.9: Demonstrate understanding of angles. In this assignment, students have to think critically about which faces will consist of parallel and perpendicular lines and which ones will show lines sloping towards the vanishing point. Beyond

understanding the meaning of parallel and perpendicular lines, they also need to have the skills to draw them accurately while having the opportunity to express their own creativity.”
