This study notes covers Worked Example: Translation 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 4 of 6 in this topic. Use this study notes to connect the idea to the wider topic before moving on to questions and flashcards.
Worked Example: Translation
Point A is at (2, 3). After a translation, it moves to (5, 7). What is the translation vector?
Step 1 Find horizontal movement
x-coordinate: 2 → 5, moved 3 right
Step 2 Find vertical movement
y-coordinate: 3 → 7, moved 4 up
Step 3 Write as vector
Vector = (3, 4)
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.
