Question 1
Question (a)
On the diagram, draw the image of
Question (i)
shape A after a translation by the vector
Question (ii)
shape A after a reflection in the line y=x+1.
On the diagram, draw the image of
shape A after a translation by the vector (−71)
Image drawn at ( -2,-3 ),
(-3,-2),(-4,-2) and
(-3, -4)
B1 for translation by (k1) or by (−7k)
shape A after a reflection in the line y=x+1.
Image drawn at (2,-3),
(3, -2), (4, -3) and (4, -4)
B2 for correct size and orientation but wrong position or for quadrilateral with 3 correct vertices
or B1 for y=x+1 drawn soi long enough to be recognised
Reflect triangle T in the line x=1.
Image at (0,1),(-3,1),(-3,2)
B1 for reflection in x=k or y=1.
Rotate triangle T through 90∘ anticlockwise about (6, 0).
Image at (5,-4),(5,-1),(4,-1)
B1 for rotation 90∘ anticlockwise with other centre or for rotation 90∘ clockwise about (6,0).
Enlarge triangle T by a scale factor of -2, centre (1,0).
Image at (-1,-2),(-7,-2),(-7,-4)
B1 for enlargement, factor -2 with other centre.
On the grid, draw the image of
triangle A after a rotation 90∘ clockwise, centre (1,-2).
Triangle at (4,-5),(6,-2),(7,-3)
B1 for correct 90∘ anticlockwise rotation
about (1,-2) or correct orientation,
wrong centre
