Question

Question 7
Check whether the given set of three numbers either a Pythagorean triplets or not ?
(i) 9,12, 15
(ii) 7, 11, 13
(iii) 10, 24, 26

Answer 1

Step-by-step explanation:

9,12,15 are pythagorean triplets as

15^2=12^2 +9^2

7,11,13 are not pythagorean triplets as

13^2 is not equal to 11^2 + 7^2

10 ,24,26 are pythagorean triplets as

26^2 = 24^2 +10^2

the all above examples can be proved by pythagorean theorem.

pythagorean triplets states that

(greater side )^2 = ( 1st side )^2 + ( 2nd side )^2 i.e

(greater side )^2 = sum of squares of other to sides
