(a) Two triangles, A and B, are shown on the grid below.
(i) Explain why triangle A and triangle B are congruent. [1]
(ii) On the grid above, translate triangle A using the vector \(\begin{pmatrix} 3 \\ -1 \end{pmatrix}\). [2]
(b) Triangle T is shown on the grid below.
(i) What type of triangle is T? [1]
(ii) On the grid below, enlarge the triangle using scale factor 3. [2]

|---|---|---|
| (i) Explains that congruent means (the triangles are) exactly the same shape and size. | E1 | |
| (ii) Correct translation of triangle A. i.e. 3 squares right and one square down. | B2 | B1 for a correct horizontal or vertical translation Correct coordinates are (7,6),(7,3) & (9,3) |
| Scheme | Marks | Comments |
|---|---|---|
| (i) Right-angled (scalene) triangle | B1 | Accept ‘right-angled’ or ‘scalene’ |
| (ii) Correct enlargement by scale factor 3. | B2 | Award B1 if correct enlargement using another scale factor. |
