WhWhich of these four sets of side lengths will form a right triangle? Set 1 10 cm, 26 cm, 24 cm Set 2 4 in., 2 in., 6 in. Set 3
Aloiza [94]

Answer:

All four Sets didn't work

Step-by-step explanation:

You should be doing hypothnose aka: a² + b² = c²

If they both equal that means they are a right triangle.

Set 1:

24² + 26² = 110²

576 + 676 = 10²

1252 = 12100

No

Set 2:

2² + 4² = 6²

4 + 16 = 6²

20 = 36

No

Set 3:

13² + 14² = 15²

169 + 196 = 15²

365 = 225

No

Set 4:

10² + 20² = 30²

100 + 400 = 30²

500 = 900

No
