The Field
The Field
12 meter arc
8 and 12 meter arcs
8 meter angle- 457= x/360 (2pi8)
12 m area- x=(180/360)2pi12
(.76 squared)= area= 1.81 m
Bounce shots are reflections, like mini golfing
In Summary
- When setting up a lacrosse field, being able to use geometry related equations is important to ensure correct proportions
- When playing lacrosse, angles are very important so the ball gets where it needs to go
Geometry in Lacrosse
Defense
8 meter arc
Crease
Goal
- rectangular field
- diagonals are congruent and bisect each other
- one half is the preimage of the other side, making the field a perfect example of isometry
-Area= LxW= 110x60 ft = 6600 sq. ft

Perpendicular to the body
At a 45 degree angle
At a 135 degree angle
Checking
What else can you do?
-find arc length of the 12
-angle measurement of the 8
shooting space- triangle
Crease circumference= 478 cm
8 meter circumference= 457 cm
12 meter sector angle= 180°
-One way to shoot is to
make a bounce shot
Volume of a sphere= 4/3pi(r cubed)
Volume= 143.8 cm3

Shooting

It is impossible to shoot at a 180 degree angle.
The best place to shoot is at a 90 degree angle, directly in front of the goal.
Places to shoot are between a 90 degree angle and a 135 degree angle.
The Goal
-Bounce shots make similar triangles
Surface area of a sphere= 4pi(r squared)
Surface area=132 cm(squared)
