How do you find scale factor?

Answer 1

Scale factor is the ratio between the length of any linear component of the image to the length of its corresponding original component.

Scaling is a transformation of objects on a plane that is characterized by (a) the center of scaling #O# (b) scaling factor #f!=0#.
If these two characteristics are know, the image of any point #A# is constructed by connecting point #O# to point #A# and finding on that line such a point #A'# that #|OA|/|OA'| = |f|# Point #A'# lies on the same side from center #O# as point #A# if #f>0# and on the opposite side form center #O# for #f<0#.

Scaling proportionally changes all the lengths of straight segments, preserves the angles and, in particular, preserves parallelism and perpendicularity between straight lines.

A concept of similarity is completely based on scaling. See UNIZOR menu items Geometry - Similarity many details, theorems and problems.

Answer 2

To find the scale factor, divide the length, perimeter, area, or volume of one object by the corresponding length, perimeter, area, or volume of a similar object.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
