Diketahui titik p(3,4) dan titik A(1,2) tentukan bayangan titik p oleh D[A,2]

Trasformasi Dilatasi D[ A(a,b), k]
x' = k (x-a) + a
y' = k(y-b) + b
P(x,y) = (3,4) –> x = 3, y = 4
A(a,b)= ( 1, 2)–> a = 1, b = 2
k = 2

x' = 2(3-1)+ 1 = 2(2) + 1 = 5
y' = 2(4-2)+2 = 2(2) + 2 = 6
Banyangan P (x1', y' ) = (5,6)
