how to solve a scale factor of a triangle​

Answer 1

Answer:

If you multiply a side from triangle ABC by 2, you get the length of the corresponding side of triangle DEF. You can also get 2 as the scale factor by finding the ratios: 12/6 = 2, 16/8 = 2, and 18/9 = 2. The ratios of the corresponding sides are all equal to 2.
