Tell whether this set of numbers is a pythagorean triple. (6, 9, 12) yes or no?

No. This does not meet the Pythagorean theory. A good and easy triple is (3,4,5) if the numbers reduce down to those numbers it’s correct. Or you can just do the simple equation a2+b2=c2. Or if you have the answer to either one of the A or B and you also have the answer to C you can easily find the answer by squaring the numbers and subtracting then you get the squared answer to the missing side. Say your adjacent side of your right triangle is 3 and your hypotenuse is 5. Square them both. So that would be 9 and 25. Subtract. 25-9= 16. Bam you found the missing side. 4. That’s also another simple way to find the sides of a right triangle that teachers usually don’t like to teach.
