Answer 2

Hmm I think you can simply compare corresponding sides on the triangles.
For example, on the solid triangle, what is the length of the left leg?

And then on the dotted triangle, what is the length of the left leg?

Answer 3

For the dotted 7 units
For the solid 3 units

Answer 4

You sure? I think it's 3 and 6.

Answer 5

@Poto Yes, as zepdrix said, you can just check the lengths. And it is 6 for the dotted.

Answer 6

If you look at the other corresponding sides, you'll find that they're 4 and 8.

Answer 7

Sorry about that i miss counted

Answer 8

It happens, you'll be fine.

Answer 9

How do you get from 3 to 6?
And from 4 to 8?

Hmm ::)

Answer 10

Add 4 and 3

Answer 11

No no, the change that you're applying has to be the same for both.
So addition isn't going to work.

What about multiplication?

Answer 12

Times 2

Answer 13

So the scale factor would be 2 i'm guessing

Answer 14

Correct!
Yay!
