Q2.
If the distance between point A and its reflected point (A') is 12 squares then which of the statements below is true?
The distance between the mirror line and A is 12 squares
The distance between the mirror line and A is 24 squares

The distance between B and B' is 4.5 squares
The distance between B and B' is also 9 squares
The distance between the mirror line and B' is 4.5 squares
Q4.

The line of reflection is vertical
The x axis is the line of reflection
The y axis is the line of reflection
Q5.

Q2.
Which statement below is correct?
Reflections and Translations always look the same
Reflections and Translations never look the same
You can easily tell if congruent shapes have been reflected or translated
Q3.
Which statement below is correct?
It is only hard to tell if a shape has been translated or reflected if the shape is a quadrilateral
It is only hard to tell if a shape has been translated or reflected if the shape is a rectangle
It is only hard to tell if a shape has been translated or reflected if the shape is regular
Q4.
Which statement below is correct?
If a right angled triangle has been reflected along the x axis then it is not obvious whether it has been reflected and not translated
If a right angled triangle has been reflected along the y axis then it is not obvious whether it has been reflected or translated
If an equilateral triangle has been reflected along the y axis then it is obvious that it has been reflected and not translated
Q5.
If the vertices of triangle A are (-5,3), (-5,1) and (-2,1) and the vertices of triangle B are (-5,-1), (-5,-3) and (-2,-3), which of the below best describes the transformation from A to B?
Reflected onto the x axis
Reflected onto the y axis
Translated down by 4 squares
