How can you tell if three positive numbers form a Pythagorean triple?
The Pythagorean thereom is a^2+b^2=c^2. So, you can tell if they
are a Pythagorean triple by seeing if the two smaller numbers
squared equal the largest number squared. Example. Are 3,4, and 5 a
Pythagorean triple? 3^2= 9. 4^2= 16. 5^2= 25. 9+16=25, so they are
a triple.
