3. Rotations

Continue to next subchapter

Exercise 4 Page 561

Only consider rotations about the origin and rotations of $9 0^{\circ},$ $18 0^{\circ}$ and $27 0^{\circ} .$

See solution.

Practice makes perfect

We will only consider rotations about the origin and rotations of

9 0^{\circ},

18 0^{\circ}

and

27 0^{\circ} .

The following rules apply.

Rotation of 9 0^{\circ} : Rotation of 18 0^{\circ} : Rotation of 27 0^{\circ} : (a, b) \to (- b, a) (a, b) \to (- a, - b) (a, b) \to (b, - a)

For any other angle of rotation, you need to use a compass.
