Siapapun mohon bantuannya dong
Jawab:
Transformasi geometris
i) Translasi T –> A + T = A'
T = A' – A
Penjelasan dengan langkah-langkah:
P(-5, -3) T(a,b)–> P'(-4,-1)
T= P' – P = {(-4 -(-5)) , -1 -(-3)}
T = { (-4 +5), (-1 +3)}
T(a,b) =(1, 2)
.
jika (x,y ) di T (1, 2) –> bayangannya :
x + 1= x' –> x = x' – 1
y+ 2 = y' –> y= y' – 2
bayangan garis x + 2y – 6 = 0 diT(1, 2) =
(x – 1) +2(y-2) – 6= 0
x - 1 + 2y – 4 – 6= 0
x + 2y – 11= 0
