Q1.
Fill in the gap: We can combine a translation and a reflection by performing one ________________ after the other.
reflection
rotation
Correct answer: transformation
translation
Q2.
State the coordinate of Vertex A after being translated by the written vector.
(-2 2)
Correct answer: (0, 8)
(4, 0)
(4,4)
