(a) Using a scale of 2cm to 2units on both axes, draw two perpendicular axes OX and OY.

(b) Plot points A(4,2), B(8,2) and C(6,8). Join the points to form triangle ABC

(c) Draw image triangle A1B1C1 of  triangle ABC under a reflection using the y-axis as mirror line. Such that      A--->A1, B--->B1 and C--->C1.

(d) Draw image triangle A2B2C2 of triangle ABC under a clockwise rotation of 90 degrees about the origin O(0,0) such that A--->A2, B--->B2 and C--->C2.

(e) Draw image triangle A3B3C3 of triangle ABC under an enlargement by scale factor -1/2, such that        A--->A3, B--->B3 and C--->C3.

(f) State the single transformation that maps (i) Triangle ABC onto triangle A1B1C1 (ii) triangle ABC onto triangle A2B2C2
