We will determine it as follows:
We will have that the coordinates of A are:
a(0, 1)
b(0, 3)
c(2, 1)
We will have that the coordiantes of B are:
a'(3, 1)
b'(3, 5)
c'(7, 1)
Now we whave the following:
ab = 2
ac = 2
bc = 2sqrt(2)
a'b' = 4
a'c' = 4
b'c' = 4sqrt(2)
Each measurement is respective witht the ones of the other triangle.
We can see that the A to B is an enlargement with a scale factor of 2.
