Answer:

similar, scale factor = 100

Step-by-step explanation:

Consider, △ABC is similar to △EFG,

Then,

AB/BC=EF/FG

4/5k=400/500

Here, scale factor k is 100.

To verify, they are similar, do this for all with scale factor k.

AB/CA=EF/EG

4/6k=400/600

Which is true,

CA/BC=EG/FG

6/5k=600/500

Which is also true, we can conclude, the triangles are similar and scale factor is 100.
