The numbers 45 28 53 form a pythagorean triple true or false

GarryVolchara [31]

You can verify this by plugging the numbers into the Pythagorean theorem, $a^2+b^2=c^2$ , where c is the hypotenuse (the longest side, in this case 53).

So it would be: $28^2 + 45^2 = 53^2$
The equation is true.
2809 = 2809
