Use the Pythagorean theorem to prove whether or not each set of numbers represent the side lengths of a right triangle.
In your final answer, include your proof.
A. 6, 12, and 15
B. 5, 12, and 13

A does NOT have lengths of a right triangle. 6²+12²≠15²

B does have lengths of a right triangle.

5²+12²=15²

Step-by-step explanation:

the Pythagorean Theorem is  "The square on the hypotenues is the sou of the squares on the opposite sides or   a²+b²=c²

So square the numbers given and see if they add up

36 + 144  = 180. The square of 15 is 225. The classic Pythagorean triple has

values of 3,4 & 5    12 & 15 are multiples of 4 & 5. ( 9 would be a good fit here.

5, 12, qnd 13 is another classic Pythagorean triple.

Go at it backwarda just for fun:  13² = 169  12² = 144.

169 - 144 = 25   That's the Square of 5.  

Voila!  Proof!

im pretty sure it would be 5 am, hope that , and give brainliest and guys if this is right then press the button and give 5 stars
