Is 2,15,17 a right triangle?
Is 1,8,4225 a right triangle?
Is 2, 6,400,9
IF the two smaller sides squared and added together equal the third (longest side) squared then it IS a right triangle
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
