4400 Higher June 2009 Paper 3 Q3
3 On the grid, enlarge triangle T with a scale factor of \(2\frac{1}{2}\) and centre (0, 0).
(3)
| Scheme | Marks |
|---|---|
| correct enlargement vertices (10, 10) (15, 10) (15, 20) | B3 |
| (3) | |
| (3 marks) |
Notes
B3: B2 for translation of correct shape
or 2 vertices correct
or for enlargement \(1\frac{1}{2}\), centre (0, 0)
B1 for one side correct length
Allow \(\frac{1}{2}\) square tolerance for both vertices and lengths of sides of triangle
