Teach it
Where it is taught, with guided notes, practice, homework, an exit ticket and an interactive Teacher Deck.
Examples
- Reflecting a figure, then translating the result, is a composition of transformations.
- A → A' → A'' shows two transformations applied in sequence.
Key rule
The order of transformations in a composition matters — doing them in a different order can give a different result.
Memory hook
One transformation, then another, in order.
