Question

Are 20, 25 and 30 an example of a Pythagorean triplet? Yes or No

Answer 1

If you can show that 20^2+25^2 = 30^2, then you will have shown that 20,25,30 is a pythagorean triple.

Answer 2

No.
20 = 5 *4
25 = 5*5
30 = 5*6
(4, 5, 6) is not a Pythagorean Triple

Answer 3

Right off the bat however, the units digit of 20^2 will be 0 and the units digit of 25^2 will be 5. These units digits add to 0+5 = 5, which is NOT the units digit of 30^2 (which is 0)

Answer 4

No If they are a Pythagorean triple, then Pythagoras's Theorem applies:
30² = 20² + 25²
But 30² = 900
And 20² + 25² = 400 + 625 = 1025. Not 900. So not a Pythagorean triple.
