Answer:
C.
Step-by-step explanation:
A Pythagorean triple are three numbers such that the sum of the squares of two smaller numbers is equal to the square of the biggest number.
A. 1^2 = 1 and 2^2 = 4 1 + 1 ≠ 4 So, not a Pythagorean triple
B. 5^2 = 25 8^2 = 64 10^2 = 100
25 + 64 ≠ 100 So, not a Pythagorean triple
C. 5^2 = 25 12^2 = 144 13^2 = 169
25 + 144 = 169 So, it is a Pythagorean triple≠
