The Pythagorean triples here are; 3, 4, 5. Option 1
What is a Pythagorean triple?
We define a Pythagorean triple as a^2+b^2 = c^2 where a, b and c are the three positive integers. Given that we can find the Pythagorean triple from; (x2 - y2)2 + (2xy)2 = (x2 + y2)2
Where; x = 2, y = 1
Substituting values have;
(2^2 - 1^2)^2 + (2*2*1)^2 = (2^2 + 1^2)^2
This results to;
3^2 + 4^2 = 5^2
9 + 16 = 25
25=25
Therefore the Pythagorean triples here are; 3, 4, 5. Option 1
