Plot triangle ABC with coordinates A(1, 1), B(3, 1) and C(1,3 )
Plot A′B′C′ the image of ABC under an enlargement scale factor 2 centre A and write down it’s coordinates
Plot A′′B′′C′′ the image of A′B′C′ under a reflection in the line x+y=0 and write down it’s coordinates
A′′B′′C′′ is then reflected in the line y=0 to give A′′′B′′′C′′′. Give the coordinates of A′′′B′′′C′′′
Describe fully a rotation that maps A′′′B′′′C′′′ onto A′B′C′
