Question

Which one of the following is not a Pythagorean triples?

• A. 11, 60, 61
• B. 16, 63, 65
• C. 28, 45, 53
• D. 30, 80, 89

Answer 1

The correct option is D 30, 80, 89

Applying the Pythagorean triples rule as $a^2+b^2=c^2$
Option A: ${11}^2+{60}^2={61}^2$
= 121 + 3600 = 3721 is a Pythagorean triples
Option B: ${16}^2+{63}^2={65}^2$
= 256 + 3969 = 4225 is a Pythagorean triples
Option C: ${28}^2+{45}^2={53}^2$
= 784 + 2,025 = 2809 is a Pythagorean triples
Option D: ${30}^2+{80}^2={89}^2$
= 900 + 6400 $\ne$ 7921 is not a Pythagorean triples.
