Selidiki segitiga berikut termasuk segitiga siku-siku,tumpul,atau lancip a.AB=17 cm,BC=15 cm,AC=8 cm b.KL=10cm,LM=25 cm,KM=30 cm c.PQ=18 cm,QS=32 cm,PS=26 cm

ūa. AB = 17 cm, BC = 15 cm, AC = 8 cm
AB^2 = BC^2 + AC^2
17^2 = 15^2 + 8^2
289 = 225 + 64
289 = 289
segitiga siku-siku

b. KL = 10 cm, LM = 25 cm, KM = 30 cm
KM^2 = KL^2 + LM^2
30^2 = 10^2 + 25^2
900 = 100 + 625
900 = 765
segitiga tumpul

c. PQ = 18 cm, QS = 32 cm, PS = 26 cm
QS^2 = PQ^2 + PS^2
32^2 = 18^2 + 26^2
1024 = 324 + 676
1024 = 1000
segitiga tumpul
