Right triangles have sides that are Pythagorean triplets. 
That is, the following relationship holds true.
{{{a^2+b^2=c^2}}}
where c is the hypotenuse and a and b are the other two sides. 
A.)3,4,5
9+16=25. 
25=25.
True
B.)5,12,13
25+144=169. 
169=169.
True
C.)8,15,17
64+225=289. 
289=289.
True
D.)12,15,18
144+225=324. 
369=324.
False 
E.)9,12,15
81+144=225. 
225=225.
