Answer:

2,3,5,6


Step-by-step explanation:

2,3,5,6

Answer:

C'Q = QC ; ⊥ A'A ; A'A || B'B ; m∠TRB = 90°

Step-by-step explanation:

Each pre-image point is the same distance from the line of reflection as the image point.  Therefore C'Q = QC.

Lines of reflection are perpendicular to pre-image and image points; this makes the third statement true.

Lines connecting pre-image points to image points are parallel; thus A'A || B'B.

Since lines of reflection are perpendicular to pre-image and image points, the sixth statement is true.
