Answer:

A reflection followed by a rotation

Explanations:

Coordinates of ABCD

A(-8, 6), B(-2, 6), C(-2, 4), D(-8, 4)

Coordinates of A'B'C'D'

A'(-8, -6), B(-2, -6), C'(-2, -4), D'(-8, -4)

The rule of transformation from ABCD to A'B'C'D' is (x y)→(x −y)

Therefore, ABCD was reflected across the x-axis to form A'B'C'D'

Coordinates of A"B"C"D"

A"(6, -8), B"(6, -2), C"(4, -2), D"(4, -8)

The rule of transformation from A'B'C'D' to A"B"C"D" is (x y)→(-y, x)

Therefore, A'B'C'D' was rotated clockwise by 270° to form A"B"C"D"

The sequence of transformation is therefore a reflection followed by a rotation
