EdexcelHigherOld spec4 marksTransformations of Shapes

Grid with x from -2 to 6 and y from -2 to 4 showing triangular flag shapes P and Q and a cross at the point (2, 0)

(a) Describe fully the single transformation that maps shape P onto shape Q. (2)

(b) On the grid, rotate shape P 90° clockwise about the point (2, 0).
Label the new shape R. (2)

Mark scheme (a)

Scheme	Marks
reflection in line \(x = 1\) (rotation (90° {anticlockwise} oe) about (1, 1))	B1 B1
	(2)

Notes

B1 B1: must be a single transformation oe for \(x = 1\)
must be a single transformation

Apart from questions 5, 7, 13c, 16b, 20, 21 and 22 (where the mark scheme states otherwise) the correct answer, unless clearly obtained by an incorrect method, should be taken to imply a correct method.

Mark scheme (b)

Scheme	Marks
flag at (4, − 1) (5, −1) (6, − 1) (5, − 2) or triangle at (5, −1) (6, −1) (5, − 2)	B2

Notes

B2: B1 for correct orientation of flag, or triangle but in wrong position
