Combined Transformations – what do I need to know?
- Combined transformations are more than one transformation, one performed after the after
- It is often the case that 2 transformations can be equivalent to 1 alternative transformation and you will be expected to spot those
- Here’s a reminder of the transformations:
- Requires an angle, direction and centre of rotation
- It is usually easy to tell the angle from the orientation of the image
- Use some instinct and a bit of trial and error to find the centre of enlargement.
- Mirror line – can be vertical (x = k), horizontal (y = k) or diagonal (y = mx + c)
- Points on the mirror line do not move
- Double reflections are possible if the mirror line passes through the object
