1. The only right triangle that I know of which has the side lengths form an arithmetic sequence is (3,4,5) or multiples thereof.
If the 8 cm leg is the shortest side, then we can find the remaining sides by proportions, namely
8 cm, 8*4/3=32/3, 8*5/3 = 40/3
If the 8 cm side is the other side, then the sides lengths are 6,8,10.
