Lesson details
Key learning points
- By understanding what changes and what is invariant, you can determine whether a transformation has occurred.
- Sometimes you might need to persevere in order to find the right transformation.
- You may be able to check your deductions by carrying out the transformation.
Common misconception
When completing an inverse translation, students may believe they need to flip the vector.
Ask students to say in words how you would return to the starting point, to highlight the direction needed and then link to the vector.
Keywords
Transformation - A transformation is a process that may change the size, orientation or position of a shape.
