Answer:
B,C
Step-by-step explanation:
So all you have to do is use the pythagorean theorem to solve this (a²+b²=c²).
Plug in the two shorter sides for a and b and the long side for c. If both sides equal the same thing then it will make a right triangle.
A) 5²+6²=9²
25+36=81
61≠81
B) 0.25+1.44=1.69
C)49+576=625
D) 100+256≠361
E)1+4≠9
