4 (a) Triangle A is shown on the grid. (i) Triangle A is mapped onto triangle B by a translation of (7 -5). Draw and label triangle B on the grid. (ii) Triangle A is mapped onto triangle C by an enlargement scale factor -2, centre (-1, 2). Draw and label triangle C on the grid. (b) Triangle P is shown on the grid. The stretch S is represented by the matrix ( 3 0 0 1) Triangle P is mapped onto triangle Q by the stretch S. (i) On the grid above, draw and label triangle Q. (ii) Describe fully the stretch S.
