A.

${a}^{2} + {b}^{2} = {c}^{2} \\ {8}^{2} + {15}^{2} = {c}^{2} \\ 64 + 225 = \sqrt{289} \\ {c}^{2} = 17cm \:$
jadi itu siku siku

b.

${a}^{2} + {b}^{2} ={c}^{2} \\ {7}^{2} + {24}^{2} = {c}^{2} \\ 49 + 576 = \sqrt{625} \\ c \: = 25cm$
jadi itu siku siku

c.

${a}^{2} + {b}^{2} = {c}^{2} \\ {9}^{2} + {12}^{2} = {c}^{2} \\ 81 + 144 = {c}^{2} \\ \sqrt{225} \\ c = 15cm$
itu segitiga siku-siku

d.

${a}^{2} \: + {b}^{2} = {c}^{2} \\ {12}^{2} + {5}^{2} = {c}^{2} \\ 144 + 25 = {c}^{2} \\ \sqrt{169} = 13 cm$
itu segitiga siku-siku
