Coordinate grid with x and y from -8 to 8 showing trapezium A with vertices (2, 1), (2, 2), (3, 2), (4, 1) and trapezium B with vertices (5, -4), (5, -3), (6, -3), (7, -4)

(a) Describe fully the single transformation that maps shape A onto shape B (2)

(b) On the grid above, rotate shape A 180° about (−1, 0)
Label your shape C (2)

Mark scheme (a)

Scheme	Marks
Allow translated translating translate Allow misspelling of the word eg translat Answer: Translation	B1
\(\begin{pmatrix}3\\-5\end{pmatrix}\)	B1
	(2)

Notes

B1: for translation (with none of reflection, rotation, enlargement, mirrored, turned, move or flipped stated)
NB Move with translation is acceptable

B1: for (vector =) \(\begin{pmatrix}3\\-5\end{pmatrix}\)

Mark scheme (b)

Scheme	Marks
Shape drawn at (−6, −1) (−4, −1) (−4, −2) (−5, −2)	B2
	(2)
	(4 marks)

Notes

B2: condone missing label
If not B2 then B1 for a correct trapezium drawn with correct orientation in wrong position or 3 points plotted correctly)
