Question

ਇਹਨਾਂ ਵਿੱਚੋਂ ਕਿਹੜੀਆਂ ਇੱਕ ਸਮਕੋਣ ਤ੍ਰਿਕੋਣ ਦੀਆਂ ਭੁਜਾਵਾਂ ਹਨ ? Which of the following are sides of a right triangle ? निम्नलिखित में से कौन सी एक समकोण त्रिभुज की भुजाएँ हैं? *

4, 4, 8

2, 3, 4

√5, 3, 2

√13, 3, 2

​

Answer 1

Answer:

√13, 3, 2

Step-by-step explanation:

The longest side = hypotenuse = √13

Other sides = 3 and 2

now, via pythagoras theorem,

(√13)² = 3² + 2²

13 = 9 + 4

13 = 13

LHS = RHS, hence proved that these are pythagorean triplets.
