Question

10/10 what is the relationship between the side lengths of the original and scaled copies? they are added by the same number they are subtracted by the same number they are divided by the same number they are multiplied by the same number

Explanation:

In the context of scaled copies (similar figures), the side lengths of the scaled copy and the original figure have a multiplicative relationship. This means each side length of the original is multiplied by a scale factor (the same number) to get the corresponding side length of the scaled copy. Adding, subtracting, or dividing by the same number does not represent the relationship in scaling (adding/subtracting would be a translation - like change, dividing by the same number is a type of multiplication by the reciprocal, but the core relationship in scaling is multiplication by a scale factor). So the correct option is the one about multiplying by the same number.

Answer:

D. They are multiplied by the same number (assuming the options are labeled A, B, C, D in order as given, with the last option being D)
