Illustration: Choose any square in the diagram and memorize its sequence number. The square as a starting point "1", move along the diagonal direction, counting the number of squares downwards (left and right are also acceptable directions) until reaching the bottom square with the highest sequence number. As illustrated: select four squares as starting points (the first sequence selects two squares; the fifth sequence selects one square in the middle; the 11th sequence selects one square below), moving along the diagonal (following the direction of the arrow) and counting the number of squares. Different colored diagonal lines indicate the direction of calculation and results based on the number of squares.

Conclusion:

R=V-(A-1)

R is not relevant with H.

This conclusion also applies to quadrilaterals.
