ENLARGEMENT AND REDUCTION OF PLANE FIGURES

Enlargementof regular plane figures can be defined as the technique of representing figures in a similar but larger shape using a given proportion. Reduction is the opposite of enlargement.

An object is enlarged when all of its dimensions are changed in the same ratio. Thus, enlargement is also called transformation. Each length of the objects is multiplied by the same number called scale factor to obtain the enlargement.

When the scale factor is less than one, the original objects is reduced i.e. Scale Factor = length of enlargement/corresponding length.
