Which triangle side lengths form a right triangle? Choose all that apply. 5, 6, 7 6, 8, 14 8, 15, 17 10, 12, 15 15, 20, 25 16, 1
yuradex [85]

Answer:

C. 8, 15, 17

E. 15, 20, 25

Step-by-step explanation:

You need to take the 2 smaller numbers as in 8 and 15 square it, so 8x8= 64 and 15x15= 225 and then add 64+225= 289 and 17x17=289 so 289=289 ✔

Again square 15 and 20, 15x15=225 and 20x20=400 add them 225+400=625

and 25x25=625 so 625=625 ✔

Hope this helped and good luck!
