operations
reflected
transformer
Q2.
Select the option that would best fill in the gaps in ORDER: Triangle A is reflected in the line M1 to give_____. A' is then _________ in the line M2 to give ______.
Correct answer: A' (middle triangle), reflected, A'' (furthest right triangle)
A' (middle triangle), translated, A''(furthest right triangle)
A'' (furthest right triangle), reflected , A' (middle triangle)

Q1.
Fill in the gap: We can combine a translation and a reflection by performing one ________________ after the other.
reflection
rotation
translation
Q2.
State the coordinate of Vertex A after being translated by the written vector.
(-2 2)
(4, 0)
(4,4)
Q3.
State the coordinate of the vertex A when the triangle has been reflected in the given mirror line.
(-4, -2)
