Identifying and fully describing a transformation

MA28-08

This lesson is coming soon.

In this lesson

Given a shape and its image with the transformation type not stated, identify whether it is a reflection, rotation, translation or enlargement, and give a complete, single-transformation description.

What it covers

  • Deciding which single transformation type (reflection, rotation, translation, enlargement) links a shape to its image, by checking size change, orientation flip, and position change in that order
  • Giving every required defining parameter for whichever type is identified
  • The explicit rule: describe ONE transformation only, never a combination, even if a combination would also work

For teachers

This GCSE Maths lesson teaches identifying and fully describing a transformation. By the end, students should be able to given a shape and its image with the transformation type not stated, identify whether it is a reflection, rotation, translation or enlargement, and give a complete, single-transformation description. It works through two worked examples and the mistakes examiners report.
