tell whether the triangle is a right triangle. Explain.
A. PQR is not a right triangle because [tex]5^{2}[/tex]+[tex]12^{2} \neq 13^{2}[/tex].
B. PQR is not a right triangle because [tex]5^{2} + 13^{2} \neq 12^{2}[/tex].
C. PQR is a right triangle because [tex]5^{2} + 13^{2} = 12^{2}[/tex] .
D. PQR is a right triangle because [tex]5^{2} + 12^{2} = 13^{2}[/tex].
