Given,
The dimension of the rectangle is 5 in x 12 in.
The diagonal of the rectangle is 13 in.
The diagram of the rectangle is,
By the pythorus theorem,
[tex]\begin{gathered} \text{Diagonal}^2=\text{bread}th^2+\text{length}^2 \\ 13^2=5^2+12^2 \\ 169=25+144 \\ 169=169 \end{gathered}[/tex]Yes the corners of the recatngle are square by the pythagorus theorem.
