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
5 Questions
Q1.
Which of the statements below is correct?
Reflection is the only type of translation
Transformations and reflections are types of translations
Transformations are a type of translation
Q2.
Which of the statements below is correct?
None of the above
When we reflect a square across the y-axis we can also translate it up/down
When we reflect a square across the y-axis we cannot also translate the original shape so it is the same as the translated square
Q3.
What would happen if we reflected a shape onto the x-axis and then onto the y-axis and then back onto the x-axis and then onto the y-axis?
None of the above, it depends on the actual shape
The shape would be translated 1 square away from the original
The shape would be translated to the left
Q4.
Which of the statements below is correct?
When we reflect a square onto the x-axis the size of the shape changes
When we reflect a square onto the x-axis we can also translate it left/right
When we reflect a square onto the x-axis, the reflected shape must pass through the origin
Q5.
Which of the statements below is NOT correct?
If we reflect a rectangle across the x-axis then we can also say that this shape has been translated either up or down
If we reflect a rectangle across the y-axis we can also say that this shape has been translated either to the left or to the right
If we reflect a right-angled triangle across the y-axis we can also say that this shape has been translated either to the left or right
