This website is by Hannah Koehler on angles, parallel lines and geometry in Field Lacrosse. It shows how parallel lines appear in lacrosse, and how they are important par of the rules while playing. It also shows the angles used to shoot the ball into the net. As well as the shapes and sizes of the net, ball and stick.
This website will help me with my project because it showed me that there is more than just the shooting angles that help with the mathematics of lacrosse. And that lacrosse has math in every play and move you make, including all the rules.
