Answer: 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!
