to test if given number defines a right triangle you have to use Pythagorean theorem \[\huge\rm a^2 +b^2 = c^2\] plug in a b and c value remember c is the longest side if right triangle if both sides are equal then yes those 3 lengths makes a right triangle

for example A) 4 . 8 , 9 c is 9 because it's the bigger number \[4^2 + 8^2 = 9^2\] solve it and let me know if both sides are equal or no :-)
