Answer:
The scale factor is 1/4.
Explanation:
Dilations
Quadrilateral A'B'C'D' is the result of dilation of quadrilateral ABCD by a scale factor.
To find the scale factor, we compare the measures of the side lengths from consecutive vertices of each quadrilateral.
From A to B, there are 4 units. From A' to B' there is one unit. This gives a scale factor of 1/4.
This happens with the rest of the measures.
From B to C there are 4 horizontal and 4 vertical units. From B' to C' there is one unit of each dimension.
This pattern can be confirmed by comparing any pair of vertices of each quadrilateral, thus we can conclude:
The scale factor is 1/4.
