e. 8, 15, 17
f. 12, 16, 20

Answer 1

a. No - 5^12 + 13^2 =/= 16^2
b. No - By definition, as 41.2 is not an integer
c. Yes - 32^2 + 60^2 = 68^2
d. No - By definition, as 17.1 is not an integer
e. Yes - 8^2 + 15^2 = 17^2
f. Yes - 12^2 + 16^2 = 20^2 (this is basically the most well known 3-4-5 triangle)
