Question

check weather 7,8,9 is a pythagorean triplet or not.​

Answer 1

$\textbf{\underline{\underline {Solution : }}}$

In the given question that is not mentioned that what is base ,hypotenuse or perpendicular So we can take it according to ourselves.

So let's put the pythagoras theorem

$= {h}^{2} = {p}^{2} + b ^{2} \\ = {9}^{2} = {7}^{2} + {8}^{2} \\ = 81 = 49 + 64 \\ = 81 = 113.$

Hence the sum of the its perpendicular or base is not equal to the square of hypotenuse so this is not pythagoras triplets:

Answer 2

Given:  Sides of a triangle

7, 8 and 9

To Find : Does these sides form a Pythagorean triplet

Solution:

Pythagorean triplet

(a,b,c)

satisfy

c² = a² + b²

where c > a,b

here given 7,8,9

9² = 81

7² = 49

8²=64

49+64=113 # 81

hence it is not a Pythagorean triplet
