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.
\(2^2+3^2=(\sqrt{13})^2 \\
4+9=13 \\
13=13 \\ true\)
b.
\(2^2+2^2=4^2 \\
4+4=16 \\
8=16 \\
not \ true\)
c.
\(1^2+(\sqrt{3})^2=2^2 \\
1+3=4 \\
4=4 \\
true\)
The answer is A and C.
