GCSE Maths Practice: transformations

Question 7 of 10

Understand the information required to fully describe a rotation.

‹ ›

\( \begin{array}{l}\text{Which information is needed to fully describe a rotation?}\end{array} \)

Choose one option:

Always specify center, angle, and direction when describing rotations.

A rotation moves a shape around a fixed point by a certain angle in a specified direction (clockwise or anticlockwise). To describe it completely, you must state the center of rotation, the angle, and the direction. This ensures the transformation is uniquely defined. Understanding rotations is important for coordinate geometry, mapping shapes, and composing transformations. Practice by rotating shapes around different points and angles on a grid to see how coordinates change.
