(a) On the grid above, rotate the shaded shape 180° about \((0, 0)\) (2)
Mike was asked to
‘Reflect shape A in the line with equation \(x = 3\)’
Mike’s answer is shown on the grid.
His answer is wrong.
(b) Explain why. (1)
| Answer | Mark | Mark scheme |
|---|---|---|
| Rotation drawn | B2 | correct shape drawn at \((-4, -2), (-2, -2), (-1, -4), (-5, -4)\) |
| (B1 | for rotation of the shape by 180° about any centre or for any 3 out of 4 vertices correct) |
| Answer | Mark | Mark scheme |
|---|---|---|
| Explanation | C1 | for explanation of why answer is wrong Acceptable examples he has reflected (in the line) \(y = 3\) / he has used \(y = 3\) he reflected shape A with equation \(y = 3\) \(x = 3\) is supposed to be vertical \(x = 3\) means the line of reflection should go through 3 on the \(x\)-axis it should be on the right of A, not beneath it correct reflection in line \(x = 3\) shown on diagram with supporting comment eg it should be here Not acceptable examples he has not reflected the shape (in the line \(x = 3\)) he has reflected in the wrong line / the reflection line isn’t on \(x = 3\) because the shape is the wrong way he drew it wrong he has used the \(y\)-axis instead of the \(x\)-axis |
