Enlargement how to find the scale factor

The scale factor corresponds to the unit rate and the constant of proportionality.Remember: For any pair of similar figures, corresponding sides are in the same ratio, and corresponding angles are equal.Determine the scale factor from the image on the left to the image on the right.Write down the coordinates of the centre of enlargement and the scale factor.The scale factor, or linear scale factor, is the ratio of two corresponding side lengths of similar figures.Similar figures have the same shape but are different sizes. The scale.

In short, the scale factor is the relationship between our printed units and our drawing units.When architects design buildings, for example, they do not produce alife-size drawing ofthe building.For example if you are given the length of one side and the scale factor and you are asked to find the length of the matching side on the new figure you should multiply.

An enlargement is done when you multiply by a scale factor all the sides of a given polygon; whereas that in a reduction you divide by this scale factor.Scale Drawings and Models A scale drawing is a proportional two-dimensional drawing of an object.Solution: We first find the matrix that corresponds to each separate transformation.


An enlargement requires a centre of enlargement and a scale factor.To find the scale factor, locate two corresponding sides, one on each figure.
