ABSTRACT
For isosceles right›angled triangle with the leg a, as it follows from Fig. 4.3, the solution can be expressed in the following way:
p(x1, y1) = 8∑ i=1
s(ξi – x1, ηi – y1, a, a). (4.110)

At last, the structure of the solution for right›angled triangle with the acute angles 30◦ and 60◦ and the hypotenuse c becomes clear from Fig. 4.4:
p(x1, y1) = 24∑ i=1
s(ξi – x1, ηi – y1, a, b), a = √
3 2 c, b =
3 2 c. (4.111)
