1. %288%5E2%29 + %2815%5E2%29 = %2817%5E2%29
64 + 225 = 289
289 = 289.
Yes number 1 is a right triangle.
==========================================
2. %285%5E2%29 + %286%5E2%29 = %289%5E2%29
25 + 36 < 81
No, number 2 is not a right triangle.
===========================================
3. %282.4%5E2%29 + %282.5%5E2%29 = %283.6%5E2%29
5.76 + 6.25 < 12.96
No, number 3 is not a right triangle.
===========================================
4. %2860%5E2%29 + %2880%5E2%29 = %28100%5E2%29
3600 + 6400 = 10000
Yes number 4 is a right triangle.
