IF the two smaller sides squared and added together equal the third (longest side) squared then it IS a right triangle

First one:

2^2 + 15^2  = 17^2 ??????   If yes, it is a right trangle according to the Pythagorean Theorem...

4 + 225 = 289

229   does NOT equal 289    so the first one is NOT a right triangle....

 

can you do the rest of them?    The third example seems like you may have too many numbers...or not enough spaces
