bayangan titik A(3,5) oleh rotasi [O,-180°], dilanjutkan rotasi [O,60°] adalah

1. Rotasi [0,-180°] = (-x,-y) dilanjutkan
2. Rotasi [0,60°] = (1/2√3y-1/2x , -1/2y-1/2√3x)

Bayangan titik A (3,5) = (5/2√3-3/2 , -5/2-3/2√3) 

rotasi [0, -180°] dilanjutkan rotasi [0, 60°]
= rotasi [0, -180° + 60°]
= rotasi [0, -120°]

(x') = (cos -120° ...... - sin -120°) (3) = (-1/2 ...... -1/2 √3) (3) = (-3/2 - 5/2 √3)
(y') ...(sin -120° ........ cos -120°) (5) ... (1/2 √3 ...... -1/2 ) (5) .. (3/2 √3 - 5/2)

Jadi A' (-3/2 - 5/2 √3, 3/2 √3 - 5/2)
