Question
Class 7MathematicsThe Triangle and Its Properties

Find whether the following triplets are Pythagorean or not?

(a) (5, 8, 17)

(b) (8, 15, 17)

Verified Answer

(a) Given triplet: (5, 8, 17)

172 = 289

82 = 64

52 = 25

82 + 52 = 64 + 25 = 89

Since 89 ≠ 289

52 + 82 ≠ 172

Hence (5, 8, 17) is not Pythagorean triplet.

(b) Given triplet: (8, 15, 17)

172 = 289

152 = 225

82 = 64

152 + 82 = 225 + 64 = 289

172 = 152 + 82

Hence (8, 15, 17) is a Pythagorean triplet.
