You will see a triangle with vertices A(1,-1), B(4,3) and C(6,2) as well as a vertical straight line x = -1. YOUR TASKS: Reflect the given triangle about the straight line x = -1. Rotate the triangle about the given point D(1, -2) 90 degrees clockwise. Rotate the triangle about the given point D(1, -2) 90 degrees anti-clockwise. Translate the triangle by using the vector v = (2, -3). [extension] Enlarge the triangle by scale factor 3, centre of enlargement D(1, -2).
