Pythagorean theorem : a^2 + b^2 = c^2

using 3,4,5
3^2 + 4^2 = 5^2
9 + 16 = 25
25 = 25 (correct)

using 8,15,17
8^2 + 15^2 = 17^2
64 + 225 = 289
289 = 289 (correct)

they are Pythagorean triplets because they satisfy the Pythagorean theorem

a^2 + b^2 = c^2

using 3,4,5

3^2 + 4^2 = 5^2

9 + 16 = 25

25 = 25 (correct)

using 8,15,17

8^2 + 15^2 = 17^2

64 + 225 = 289

289 = 289 (correct)
