Summary

Sample Flashcards

180° Rotation
(x,y) → (-x,-y). Both coordinates change sign. Same clockwise or anticlockwise!
Describing Rotations
Must state THREE things: Centre (coordinates), Angle (90°/180°/270°), Direction (CW/ACW except for 180°).

Exam questions for Transformations: Rotations

To fully describe a rotation, which three pieces of information are needed?

  • A. Angle, direction and mirror line
  • B. Centre, angle and direction
  • C. Centre, scale factor and direction
  • D. Column vector, angle and centre
