Triangle ABC with side lengths of 3, 4, and 5 has been dilated and now has side lengths of 12, 16, and 20 respectively. What was the scale factor?

______


PLEASE HELP!

Respuesta :

1. Divide the new dimension by the original dimension:

2/8 = 1/4

3/12 = 1/4

6/24 = 1/4

The scale factor was 1/4 scale

2. Same steps as number 1.

12/3 = 4

16/4 = 4

20/5= 4

The scale factor was 4
