The triangles below are similar from A to B. What is the scale factor? * 5/4
3/5
2/3
4/5

  The scale is 5/4

Step-by-step explanation:

To determine the scale factor, you have to locate which sides are similar to each other .

the side length with 20 is congruent to 16

15 is similar to 12    and 10 is similar to 8.

And to get from triangle A to triangle B of any side length, we need to multiply by a certain number which is the scale factor.

And to  find that number we will divide the side length of any side in triangle A  by the similar side to it in triangle B.

20/ 16 = 5/4

15/ 12 =  5 / 4

10 / 8 = 5/4

step-by-step explanation: yes
