Question 1183713
<br>
The SCALE FACTOR between similar figures is the ratio of the lengths of any corresponding linear measurements in the two figures.<br>
Pick the lengths of any corresponding sides in the given figure and form the ratio.<br>
Note that the question specifies the scale factor from larger triangle to smaller, so make sure you put the two lengths you choose in that correct order.<br>
Expressing the ratio in simplest terms is optional, unless instructions somewhere state that it is required.<br>
