Refleksi = pencerminan.
jarak benda ke cermin
=
jarak cermin ke bayangan
3
refleksi terhadap matematika dibagi menjadi beberapa jenis yaitu:
1. Refleksi terhadap sumbu y
4
2. Refleksi terhadap sumbu x
5
Refleksi terhadap titik asal (0, 0)
6
4. Refleksi terhadap garis y=x
7
5. Refleksi terhadap garis y = -x
Contoh : tentukanlah bayangan titik A(2, 4) jika direfleksikan terhadap garis y = -x
8
6. Refleksi terhadap garis x=a
9
7. Refleksi terhadap garis y=b
10
8. Refleksi terhadap titik p(a, b)

Latihan.
1. tentukanlah bayangan titik B(-2, 7) oleh refleksi berikut
a. sumbu x
b. garis y=-x
c. garis x=-5
2. Bayangan titik A oleh refleksi terhadap garis x=-1 adalah A'(5, 1). Tentukanlah bayangan titik A, jika direfleksikan terhadap titik (0, 0)
