transformasi geometri

• translasi

koordinat titik sudut bayangan ∆ABC :

A' = A + T

A' = (8,3) + (-8,1)

A' = (8 + (-8) , 3 + 1)

A'(0,4)

B' = B + T

B' = (5,-3) + (-8 + 1)

B' = (5 + (-8) , -3 + 1)

B'(-3,-2)

C' = C + T

C' = (10,-2) + (-8,1)

C' = (10 + (-8) , -2 + 1)

C'(-2,-1)

Jawaban:

A' (0,4) B'(-3,-2) C'(2,-1)
