-You can **rotate** the turtle along the three axes x, y and z. We can see an example of the rotation tool on the right with the possible rotations in colors: x=red, y=blue and z=green. In the turtle geometry we can rotate these axes with the commands ''RL(angle)'', ''RU(angle)'' and ''RH(angle)''. RL rotates around the local X-axis (the red circle in the picture), RU around the Y-axis (the blue circle) and RH around the Z-axis. If we imagine to look from the perspective of the turtle, the names make more sense: RL rotates to the __l__left (with negative values to the right), RU rotates __u__p and RH rotates around the __h__head axes. +You can **rotate** the turtle along the three axes x, y and z.
