Shape C
Shape D
Q2.
Describe the transformation from Shape D to Shape C.
Reflection in the x axis
Reflection in the y axis
Translation 4 right and 1 up
Translation 7 left and 1 down
Q3.
Two students are describing the transformation of Square X on to Square Y. Shivani says that it is a reflection in line 𝑥=2. Mohammed says that it is a rotation 180° about (2,2) in either direction. Who is correct?
Mohammed only
Shivani only
They are both incorrect.
Q4.
Emmanuel claims that you can only describe the transformation of the shaded squares on to each other through translation. Is this true or false?
True
Q5.
Select all the options below that correctly describe the single transformation from Rectangle A to Rectangle D?
Reflection in the x axis followed by a reflection in the y axis
Translation 4 down and 4 left
