| Explanation | 3 | M1 for recognition of sum to \(360^\circ\) A1 for eg sum to 350 or subtraction to 100 or difference of 10 C1 (dep on at least M1) for correct explanation supported by their figures and working |
| Answer | Mark | Notes |
|---|---|---|
| Tessellation | 2 | B2 for at least 6 correct shapes (including the initial shape) correctly tessellating (B1 for at least 4 correct shapes, including initial shape, correctly tessellating ignore any additional sections attempted, gaps or incorrectly shaped tiles) |
