Answer/Explanation PLEASE!! :-)

Answer 1

what do you mean by a pythagorean triplet ?

Answer 2

The triplets are written in the form \(a,b,c\). The only work you have to do is to check if \(a^2 + b^2 = c^2\). Okay?

Answer 3

well actually you dont have to check by that method,,it'll take more time..there's another shortcut which i shall tell if she follows me up..

Answer 4

i wont say shortcut,,its actually quite obvious method,,

Answer 5

Yep. I know that little shortcut ;)

Answer 6

Well. I just don't want to confuse the asker, so I am going pretty basic.

Answer 7

hmm.. :|

Answer 8

I prefer Parth's explanation.
A Pythagorean triple follows the rule that squaring the two smaller numbers and adding them up results in the square of the larger number. Or in other words,
a^2 + b^2 = c^2

Answer 9

so @dumbo123 ,,what can you infer from 20,21 and 29 being pythagoras triplets?

Answer 10

yep..method's hardly any problem..
i was just trying to make use of what info is given in the ques..

Answer 11

Sometimes, there are those 'Can these be the sides of a right triangle?'... they are just the same.

Answer 12

so it would be B! Thank you guys!

Answer 13

Yes! Good job =)
