Question

Titik (2,1) direfleksikan terhadap garis x=3, kemudian direfleksikan lagi terhadap garis y=3, maka bayangannya...

Answer 1

(2,1) refleksi thd x = k = 3
x' = 2k - x = 2.3 - 2 = 4
y' = y = 1

Bayangan_pertama = (4,1)

(4,1) refleksi thd y = k = 3
y' = 2k - y = 2.3 - 1 = 5
x' = x = 4

Bayangan_akhir = (4,5)
