3. Rotations

Continue to next subchapter

Exercise 4 Page 561

Only consider rotations about the origin and rotations of 90^(∘), 180^(∘) and 270^(∘).

See solution.

Practice makes perfect

We will only consider rotations about the origin and rotations of 90^(∘), 180^(∘) and 270^(∘). The following rules apply.

Rotation of 90^(∘):& (a,b) → (- b,a) Rotation of 180^(∘):& (a,b) → (- a,- b) Rotation of 270^(∘):& (a,b) → (b,- a) For any other angle of rotation, you need to use a compass.
