      2 Marking of ground — [...] A five yard square shall be marked in front of each goal, having the goal posts at adjacent angles. A five yards square shall be marked out in front of each point space, having a goal post and a point post at adjacent angles. There will be thus formed in front of scoring area a parallelogram fifteen yards by five yards.
