'Peg Rotation' printed from https://nrich.maths.org/
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."
