Question

which of the following triplets are Pythagorean a 18,80,82. b 16 63 65 c 12 35 38

Answer 1

3 numbers say, a , b, and c, are said to be Pythagorean triplet is a^2 + b^2 = c^2, where c is the longest side of the right triangle
Now let's answer your question
a) 18, 80, 82
18^2 + 80^2=324+6400=6724
& 82^2=6724
so it is a Pythagorean triplet

b)16, 63, 65
16^2+63^2=256+3969=4225
& 65^2=4225
so it is a Pythagorean triplet

c) 12, 35, 38
12^2+35^2=144+1225=1369
& 38^2=1444
So it is not a Pythagorean triplet.
