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°).

Sample Questions

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

Shape A has vertices at (2, 1), (4, 1) and (4, 3). Shape B has vertices at (−1, 2), (−1, 4) and (−3, 4). Fully describe the single transformation that maps shape A onto shape B.
