Solution:
we are given that
In the image, shape ABCD is similar to shape WXYZ.
we have been asked to find the measure of side ZW.
As we know that when two shapes are similar then the ratios of their corresponding sides are equal.
So we can write
Hence ZW=4.5 Inches.
To solve this problem you must apply the proccedure shown below:
1. You have the following points given in the problem above:
2. To find the midpoint, you must apply the formula that is used for calculate it. This is:
Where:
3. Now, you must substitute these values into the formula for calculate the midpoint, as following:
Therefore, the answer is:
