(a) Reflect triangle A in the \(x\)-axis. (2)
(b) Draw an enlargement, scale factor 3, of shape B. (2)
| Answer | Mark | Notes |
|---|---|---|
| Triangle with vertices (2,1) (2, 4) (4,4) | 2 | B2 for triangle with vertices (2,1) (2,4) (4,4) (B1 for triangle reflected in any line parallel to \(x\)–axis or for correct reflection in \(y\) axis (triangle at (−2,−1) (−2,−4) (−4,−4)) ( B1 for a configuration which is the original triangle reflected successively in the \(x\) and \(y\) axes to give 3 triangles) |
| Answer | Mark | Notes |
|---|---|---|
| Enlarged shape | 2 | M1 for any 3 sides enlarged correctly A1 for correctly enlarged shape (SC : B1 for correct enlargement with a scale factor of 2 or 4 or for a geometrically correct shape in a wrong orientation) |
