Which lengths would form a right triangle? 9, 12, and 14 24, 7, and 26 21, 16, and 12 30, 24, and 18

The pythagorean theorem can be used only on right , when subbed into the pythagorean theorem a^2 + b^2 = c^2 , if it makes this equation true, then it is a right trianglea^2 + b^2 = a and b are the legs and c is the hypotenuse (the longest in : a = 18, b = 24 and c = 3018^2 + 24^2 = 30^2324 + 576 = 900900 = 900 (correct)so ur answer is : 18,24, and 30 form a right triangle
