Question

Determine whether the dilation from A to B is an enlargement or a reduction. Then find the scale factor of the dilation. 15. 10 16. y A

Answer 1

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.
