The shape A is drawn on the coordinate grid as shown below.

Sally and Eddie each transform the shape A onto shape B.

• Sally uses a reflection in the line y = 7 followed by a rotation of 90o anticlockwise about the point (9,9).
• Eddie transforms shape A first with a reflection in the line $$y = x$$ followed by his favourite transformation.

(a) Draw and label shape B.

(b) Describe fully Eddie's favourite transformation.
