Jamie from St John's School told us:

1) It is flipped over from North to South.
2) It is rotated 90 degrees clockwise.
3) It is rotated 90 degrees anti-clockwise.
4) It is flipped over from East to West.

Nik from Radley Primary School agreed with Jamie's answers, but also had some alternative ways of describing the transformations:

The first square can be flipped north-south or flipped east-west and then turned 180 degrees clockwise.
The second square can be turned 90 degrees clockwise or turned 270 degrees anti-clockwise.
The third square can be turned 270 degrees clockwise or turned 90 degrees anti-clockwise.
The fourth square can be flipped east-west or flipped north-south and then turned 180 degrees clockwise.

For the triangular challenges, Callum from St. Patrick's R.C. told us:

"The triangle is turned:
1.Anti-clockwise for one turn, or clockwise for two turns.
2.Clockwise for one turn, or anti-clockwise for two turns."
