Use the formula 

a^2 + b^2 = c^2

where 'c' is the hypotenuse and the longest side

I dont know how

jim_thompson5910 · Answer

For instance, in the second choice with "28,26,12", the longest side is 28, so...

a = 12

b = 26

c = 28



a^2 + b^2 = c^2


12^2 + 26^2 = 28^2


144 + 676 = 784


820 = 784


Since that last equation is false, this means that these side lengths do NOT form a right triangle


So choice B is out

Option A is a confirmed right triangle..... Use pythagoras theorem.... 
c^2=a^2+b^2             here.... a=198.b=40....and c should be 202
      =39204+1600
c^2=      40804
take square root... c=202
