Englargement in Maths

An enlargement in maths is a transformation of a plane or a solid shape where it is mapped onto a similar shape using a centre of enlargement (origin).

A'B'AB=B'C'BC=A'C'AC

OB'OB=OA'OA=OC'OC

The scale factor of an enlargement is the ratio of the lengths of the shape to those on the image.

Or the scale factor can be viewed as the ratio of the distance between the center of origin and the original shape and corresponding distance between the center of origin and the image.
