The roots of the game of lacrosse have been traced to the First Nations cultures of the Eastern Woodlands. The game originated about 1000 years ago. Lacrosse was recognized by an act of Parliament in 1994 as Canada’s national summer sport. Lacrosse is a vigorous game enjoyed by men and women across Canada!
The graphic shown is of a contemporary lacrosse stick. The webbing of the geometric design changes from the pocket to the shooting string to make it easier to either cradle or shoot the ball. The parallel lines, four-sided figures, and the repeated angles in the webbing illustrate that geometry plays an important role in sports equipment.
In this module you will explore the geometry of angles. In particular, you will investigate how they are defined, measured, classified, duplicated, and bisected. As well, you will explore relationships among the angles formed when two parallel lines are cut by a third line. In each case, you will apply definitions and relationships to solve a variety of practical problems. Some of these problems will include sports or the arts—the focus of the Unit 3 Project.
In this module you will be further developing your skills, so be prepared to be active as you investigate the following questions:
-
How are angles defined, measured, classified, duplicated, and bisected?
-
What are the relationships among the angles formed when two parallel lines are cut by a third line?
