Diketahui titik A (-1,2) dicerminkan terhadap sumbu x maka hasil pencerminannya adalah … A. (1,2)

Akreditasi.org, Hai teman-teman sekarang contoh soal yang akan kita bahas adalah tentang pencerminan pada sumbu X dan Y serta hasilnya bagaimana. Berikut ini soal yang dimaksud.

Soal:

Diketahui titik A (-1,2) dicerminkan terhadap sumbu x maka hasil pencerminannya adalah … A. (1,2)

(−1,−2)
(1,−2)
(2,1)

Jawabannya adalah B.

Pembahasan:

Perhatikan penjelasan berikut.

Jika titik A(x, y) dicerminkan terhadap sumbu X, maka bayangannya adalah A'(x, -y). Sehingga: A(-1, 2) ————> A'(-1, -2). Jadi, hasil pencerminannya adalah A'(-1, -2).

Nah, itulah pembahasan tentang soal di atas. Semoga pembahan yang kita berikan ini bisa bermanfaat untuk kita semua, terima kasih.
