Each figure shows a pair of similar triangles, one contained in the other.
Alecsey [184]

Dilation involves enlarging or reducing the size of a shape.

The scale factor of dilation is 1/6

From the complete question, the side lengths of corresponding sides of both triangles are:

AC =18cm

AC' =3cm

This means that, the larger triangle is ABC, while the smaller triangle is AB'C'.

So, the scale factor of dilation from the larger triangle to the smaller triangle is:

k = \frac{AC'}{AC}

This gives

k = \frac{3cm}{18cm}

Remove the common units

k = \frac{3}{18}

Reduce fraction

k = \frac 16

Hence, the scale factor of dilation is 1/6
