Question

2012What is the scale factor if triangle ABC was dilatedto create triangle DEF?21/27/310/3

Answer 1

2

Explanation:

Hello!

We can look at the side lengths of AB and DE because they are transitive sides.

DE is twice the length of AB, so the scale factor would be 2.

We can check because AC is transitive to DF, and BC is transitive to EF. The multiplier from ΔABC to ΔDEF is 2.

A dilation is a type of transformation that changes the size of an object by multiplying it by a scale factor.
