7 Triangle A is drawn on the grid. (a) Transformation P is represented by the matrix (-2 0 0 -2) P maps triangle A onto triangle B. (i) Draw and label triangle B. (ii) Describe fully the single transformation P. (iii) Write down the ratio area of triangle A : area of triangle B. (b) Transformation Q is represented by the matrix (1 0 0 -1) Q maps triangle B onto triangle C. Draw and label triangle C. (c) Transformation Y is represented by the matrix ( 1 0 0 3) Y maps triangle A onto triangle D. Find the matrix that represents the transformation that maps triangle D onto triangle A.
