Scaled Copies

A scaled copy is a figure that is similar to another figure but is either larger or smaller by a certain scale factor.

A scale factor is a number that scales, or multiplies, some quantity. It is the ratio of the lengths of two corresponding sides of two similar figures.

The scaled copy is twice the size of the original figure.

Two figures are similar if they have the same shape but may differ in size. Their corresponding angles are equal, and their corresponding sides are in proportion.

To determine if one figure is a scaled copy of another, check if the corresponding angles are equal and the sides are in proportion.

The scale factor is 2.

The scaled copy is one-third the size of the original figure.

The side length AB on the scaled copy corresponds to side length HJ on the original image.

Yes, Figure B is a scaled copy of Figure A.

The area of the figure increases by a factor of 4 (2 squared).
