size (Congruent)
- Direction and angle
- Points are written as
Co-ordinates
- Rotational symmetry

(Similarity)
Anmerkungen:
- Similar shapes have the same proportions and angles but can be larger or smaller
- Angle sizes remain constant
- Fractions Reduce
- Numbers bigger than 1 Enlarge
- Translation
(slide)
- Orientation never changes
