Show transcript
Each length in the shape is multiplied by the scale factor.
Each vertex in the object is a given distance from the centre of enlargement.
This distance is also multiplied by the scale factor to give the distance of the image's vertex.
A positive fractional scale factor produces an image that is smaller than the original.
To enlarge, you need the centre of enlargement and a scale factor.
