Soal Matematika Kelas 8 Hal 31,32 Ayo Kita Berlatih 6.3 Tentukan Jenis Segitiga dan Tripel Phytagoras

      _______________
= V(-15)^2 + (30)^2
     ________
= V225 + 900

= V1.225

= V225.5

LM = 15V5
           ___________________
KM = V(x3-x1)^2 + (y3 - y1)^2

           ___________________
KM = V(24 - 6)^2 + (18-(-6))^2

KM = V182 + 24^2

KM = V324 + 576

KM = 900

KM = 30

KL = LM = 15V5

KM = 30
