GEOMETRY • ROTATION 263
Make a rotation creation
All you need to make your own rotation pattern is some card
and paper, a pin, a pair of scissors, and a pencil.
Draw a simple
shape onto
card and cut it out.
Put a pin through the
the shape to make
the centre of rotation.
Pin the shape to
some paper and
draw round the outline.
TRY IT OUT
Seven rotations
45° Angle of rotation
Four rotations
72° Angle of rotation
Eight rotations
40° Angle of rotation
Rotation patterns
We can make patterns by rotating a shape lots of
times around the same centre of rotation. This T
shape makes different patterns depending on the
centre and angle of rotation we choose.
Rotate the shape a little
and draw round it again.
Repeat until you have a pattern
you like!
