Explanation:
for this the Pythagoras equation must be true :
c² = a² + b²
c is the Hypotenuse the dude opposite of the right angle in a right-angled triangle.
as such it had to be the longest side.
so, c = 26
and we get
26² = 24² + 25²
676 = 576 + 625 = 1201
wrong, 1201 is not equal to 676, so, 24, 25, 26 are NOT a pythagorean triplet.
the initial statement is false.
