In a right triangle the sum of the squares of the lengths of two shorter sides is equal to the square of the length of the longest side.

a.
[tex]2^2+3^2=(\sqrt{13})^2 \\ 4+9=13 \\ 13=13 \\ true[/tex]

b.
[tex]2^2+2^2=4^2 \\ 4+4=16 \\ 8=16 \\ not \ true[/tex]

c.
[tex]1^2+(\sqrt{3})^2=2^2 \\ 1+3=4 \\ 4=4 \\ true[/tex]

The answer is A and C.
