Quadrilateral

is a scaled copy of quadrilateral

What scale factor takes quadrilateral

to quadrilateral

A scaled copy of a figure has the same shape as the figure but is a different size.

The angle measures of a scaled copy are equal to the corresponding angle measures of the figure.
The side lengths of a scaled copy can be found by multiplying the corresponding side lengths in the figure by the same number. This number is called the scale
factor.

To find the scale factor from quadrilateral

to quadrilateral

first identify a pair of corresponding sides.

You know that 9 times the scale factor is equal to 27. Write and solve an equation for the scale factor,

Divide both sides by 9

Simplify

So, the scale factor is 3.
