6. Pencerminan terhadap garis x = h

T (x ,y ) X = h T’ ( 2h-x , y )

contoh

T (3 ,-4) X = 5 T’ (2 (5)-3, -4 )

T (3,-4) T’ (10-3,-4)

T(3,-4) T’ (7,-4)

7. Pencerminan terhadap garis y = h

U (x , y) Y = h U’ ( x , 2h- y)

contoh

U (-6, 5) Y =3 U’ ( -6 , 2(3) -5)

U (-6, 5) U’ (-6 , (6-5))

U ( -6 ,5) U’ (-6 , 1 )
