Which line segment could create a right triangle

C) 18, 24, 30

Step-by-step explanation:

In order to figure this out, use Pythagorean theorem since it's a right triangle.

Remember that the legs are shorter than the hypotenuse but when added together are longer. In this case, the two smaller values are the legs and the longer value is the hypotenuse.

A) 24, 30, 35

24² + 30² = 35²

576 + 900 = 1225

1476 = 1225 ; NOT true

B) 12, 18, 30

12² + 18² = 30²

144 + 324 = 900

468 = 900 ; NOT true

C) 18, 24, 30

18² + 24² = 30²

324 + 576 = 900

900 = 900 ; TRUE

D) 18, 24, 35

18² + 24² = 35²

324 + 576 = 1225

900 = 1225 ; NOT true

Therefore, C is the only one that works
