Question

Triangle ABC is dilated about the origin to create triangle A′B′C′.

Determine the scale factor used to create the image.

three fourths
2
one half
2.5

Answer 1

no one know this one but it is 16

Answer 2

The scale factor for the transformation of the triangles shown in the graph is 2

How to estimate the scale factor of the dilation

From the question, we have the following parameters that can be used in our computation:

The transformation of the triangles

By definition, the scale factor is simply the ratio of sides of two corresponding figures

So, the scale factor (S) would be:

S = Big triangle/Small triangle

The actual measurements are given as

Big triangle = 16

Small triangle = 8

Substitute the known values into the equation

S = 16/8

Evaluate

S = 2

Hence, the estimated scale factor is 2
