1.translasi: A(x,y) -> T(a,b)-> A' (x+a,y+b)
2.refleksi
sumbu x: A(x,y)->C sumbu x -> A' (x,-y)
sumbu y: A(x,y) -> C sumbu y -> A' (-x,y)
titik 0(0,0): A (x,y) -> C 0(0,0) -> A' (-x,-y)
sumbu x=k: A (x,y) -> C sumbu x=k -> A' (2.k - x,y)
sumbu y=k: A (x,y) -> C sumbu y=k -> A' (x, 2.k - y)
sumbu y=x: B (x,y) -> C sumbu y=x -> B' (y,x)
sumbu y=-x: C (x,y) -> C sumbu y=-x -> C' ( -y,x)
3. rotasi
rotasi 90°: C (x,y) -> R[0,90°] -> C' (-y,x)
rotasi -90°: D (x,y) -> R[0,90°] -> D' (y,-x)
rotasi 180°: E (x,y) -> R[0,180°] -> E' (-x,-y)
F (a,b) -> R[(x,y), 90°] -> F' (x+y-b, y-x+a)
4. dilatasi
A (a,b) -> D[(0,0), k] -> A' (k.a, k.b)
B (a,b) -> D[(x,y), k] -> B' (x+k (a-x), y+k (b-y))
