sides 17,21,25.
  
172 + 212 = 252
289 + 441 = 625
      730 = 625
       Nope!
sides 8,9,13
82 + 92 = 132
64 + 81 = 169
    145 = 169
       Nope!
sides 24,26,10
Put them in order smallest to largest
sides 10,24,26
102 + 242 = 262
100 + 576 = 676
      676 = 676
       Yep!
sides 1,2,3
12 + 22 = 32
1 + 4 = 9
    5 = 9
     Nope!
