Abstract: This paper concerns with the problem of obtaining pairs of pythagorean triangles, where, in each pair, the difference between their perimeters is represented by 6174(Dhuruva number of order 4),61974,82962,63954(Dhuruva number of order 5), 631764(Dhuruva number of order 6). Also, we present the number of pairs of primitive and non-primitive Pythagorean triangles

Keywords: Pairs of Pythagorean triangles, Dhuruva number, primitive and non-primitive Pythagorean triangles. 2010 Mathematics Subject Classification: 11D09, 11Y50, 11-04.
