Correct rotation.
B2
Allow B1 for one of the following:
two correct vertices
a 90° anticlockwise rotation about the origin
a correct rotation with only one other incorrect rotation seen.
In the original mark scheme the B2 answer is shaded green (shown dark grey here), the B1 example is red with a cross through it (shown light grey).

Correct reflection in \(x = -2\)
B2
B1 for one of the following:
line \(x = -2\) drawn (do not award this B1 for one side of a triangle drawn on the undrawn line \(x = -2\))
correct reflection in line \(y = -2\)
a correct reflection with only one other incorrect reflection seen.
In the original mark scheme the B2 answer is shaded green (shown dark grey here), the B1 example is red with a cross through it (shown light grey) and the line x = –2 is green.
