The calculated estimate of the scale factor is 1.5
How to estimate the scale factor of dilation
From the question, we have the following parameters that can be used in our computation:
- The actual figure is AB
- The dilation is AC
- The center of dilation is A
By definition, the scale factor is simply the ratio of sides of two corresponding figures
So, the scale factor (S) would be:
S = AC/AB
The actual measurements are not given; so, we will make use of estimates
The estimates to use are:
AB = 1
AC = 1.5
Substitute the known values into the equation
S = 1.5/1
Evaluate
S = 1.5
Hence, the estimated scale factor is 1.5
