Refleksi (Reflection/Mirroring) Soal Transformasi Geometri Kelas 9

Di kelas 9, kamu bukan sekadar "menggeser gambar". Kamu sedang belajar . Dan kabar baiknya: tidak serumit yang dibayangkan.

Perhitungan:

[ x' = \frac12 \times (-2) = -1, \quad y' = \frac12 \times 6 = 3 ] [ F'(-1, 3) ]

Titik ( B(2, -1) ) dicerminkan terhadap sumbu Y, lalu hasilnya dirotasi ( 90^\circ ) berlawanan arah jarum jam dengan pusat O(0,0). Tentukan koordinat akhirnya. For students searching for this article provides a

: [ (x',y') = P + k \cdot \big( (x,y) - P \big) ] [ (x',y') = (2,3) + 3 \cdot ( (4-2), (6-3) ) ] [ = (2,3) + 3 \cdot (2,3) = (2,3) + (6,9) = (8,12) ]
