Penjelasan dengan langkah-langkah:
s = √4² + 3²
s = √16 + 9
s = √25
s = 5 cm
__
L = 1/2 × a × t
L = 1/2 × 3 × 4
L = 3 × 2
L = 6 cm²
k = s1 + s2 + s3
k = 4 + 3 + 5
k = 7 + 5
k = 12 cm
S = 5
L = 6
K = 12
Diketahui segitiga siku-siku dengan ukuran sebagai berikut:
sisi tinggi = 4 satuan dan sisi alas = 3 satuan
sisi miring = s
Apabila digunakan theorema phytagoras:
(sisi miring)² = 4²+3²
sisi miring = √(16+9)
sisi miring = 5 satuan.
Jadi nilai S = 5.
Luas segitiga = L
L = (0,5)(alas)(tinggi) = (0,5)(3)(4) = 6
Keliling = K
K = 4+3+S = 4+3+5 = 12
