This introduction covers Moving Shapes Around within Transformations for GCSE Mathematics. Revise Transformations in Geometry & Measures for GCSE Mathematics with 16 exam-style questions and 5 flashcards. This topic appears regularly enough that it should still be part of a steady revision cycle. It is section 1 of 6 in this topic. Use this introduction to connect the idea to the wider topic before moving on to questions and flashcards.
Moving Shapes Around
When you slide your phone across a table, that's a translation. When you look in a mirror, that's a reflection. When you spin a fidget spinner, that's a rotation. When you zoom in on a photo, that's an enlargement. These four transformations are how we move and resize shapes in maths!
Practice questions for Transformations
A translation is described by the vector (3, −2). What does this mean?
Shape A is mapped to shape B by a translation. Describe fully what information is needed to describe a translation.
Quick recall flashcards
Rotation
State CENTRE, ANGLE, and DIRECTION (CW/ACW). Shape turns around fixed point. 180° is same CW or ACW.
Reflection
State the MIRROR LINE (equation). Shape flips over. Points and images are equidistant from mirror line.
