1/5

Q2.Which statement below is correct?

Reflections and Translations always look the sameYou can easily tell if congruent shapes have been reflected or translatedIt is easier to tell if a shape has been translated or reflected if the vertices are marked in a colour or labelledReflections and Translations never look the same

2/5

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 rectangleIt is only hard to tell if a shape has been translated or reflected if the shape is a quadrilateralIt is only hard to tell if a shape has been translated or reflected if the shape is regularNone of the above

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 translatedIf a right angled triangle has been reflected along the y axis then it is not obvious whether it has been reflected or translatedIf an equilateral triangle has been reflected along the y axis then it is obvious that it has been reflected and not translatedIf an equilateral triangle has been reflected along the y axis then it is not clear whether it has been reflected or translated
