Enlargements About a Centre
- Helen Bates
Section 1 - Allows the showing or hiding of information to promote students coming to their own awarenesses of the differences between standard enlargements and enlargements about a centre. Section 2 - The shapes can be moved to show that the COE can move. SEction 3 - Shows how moving the COE does not change the effect of the scale factor (i.e. dimensions are preserved - but shape positions change).
