Task Name : Golf Course Angles 
Task Level : I (Year 8) 
Semester : 2 
Topic : Angles 
VC Strand : Geometric Reasoning 
Web Address : http://maths.crusoecollege.vic.edu.au/grI

Equipment Needed : Stiff card (a roll of corrugated cardboard is usually purchased), rulers, protractors. 
Victorian Curriculum outcome : Establish properties of quadrilaterals using congruent triangles and angle properties, and solve related numerical problems using reasoning 
Task description : Use the holes created in level H or create new holes: kite, trapezium, parallelogram and rhombus. Divide each quadrilateral into two. Use rules for congruence to decide if the triangles that form the quadrilaterals are congruence. Use a different rule for each quadrilateral (SSS, SSA, ASA, student’s choice for the 4th shape). 
Assessment options : Photographs of Golf Course Holes 
Teacher notes : Students tend to make the holes too small to measure accurately: a hole should be around half the size of an A4 sheet of paper. Encourage students to use colour or even little props to make their holes a bit more interesting and creative.
