Three non-primitive Pythagorean Triples:
(3 x 5-12-13 =) 15-36-39
(3 x 3-4-5 =) 9-12-15
(5 x 3-4-5 =) 15-20-25
Two primitive Pythagorean Triples:
8-15-17
15-112-113
And a partridge in a pear tree!

one can count like this
hypotenusee 15
one triangle 9,12,15
one base 15
say another base b and hypotenus x
15^2+b^2 = x^2
or (x-b)(x+b) = 15^2 = 1* 225, 3*75,5*45,, 9*25,15*15
15*15 ruled out so 4
x-b = 1 x+b = 225 gives 113,112,15
x-b = 3 x+b = 75 gives 39,36,15
x-b = 5, x+b = 45 gives 25,20,15
x-b= 9 x+b = 25 gives 17,8,15
so there are 5 triangles above 4 and (10.12.15- mentioned on top)

You're talking about Pythagorean triples. I found five:
9 12 15
15 20 25
15 36 39
8 15 17
113 112 15
I think that's about it.

millions of them.
x^2 + 15^2 = h^2
can't have 15 as hyp.
