Question

Determine whether the dilation from A (blue figure) to B (green figure) is an enlargement or reduction, then find the scale factor of the dilation
a. enlargement; scale factor of 2
b. enlargement; scale factor of 4
c. reduction; scale factor of 1/4
d. reduction; scale factor of 1/2

Answer 1

So from the blue triangle to the green triangle, we can see that the green triangle is smaller, therefore eliminating options A and B.

Now to find the scale factor, use one of the sides of both triangles. In this case, I'll be using the bases of both. The blue triangle's base is 10, while the green is 5.

Using this info, we can make the fraction $\frac{5}{10}$ , which can be further simplified to $\frac{1}{2}$ . This is the scale factor.

In short, the answer is the last option.
