11 Here is a triangle S drawn on a grid of squares.
(a) On the grid, reflect triangle S in the line with equation \(x = 5\)
Label the new triangle T. (2)
Label the new triangle T. (2)
(b) On the grid, reflect triangle T in the line with equation \(x = 2\)
Label the new triangle U. (1)
Label the new triangle U. (1)
(c) Describe fully the single transformation that maps triangle S onto triangle U. (2)
