The length of the side between the vertices A′ and B′ is 16/7 units.
<h3>Transformation</h3>Transformation is the movement of a point from its initial location to a new location. Types of transformation are<em> reflection, translation, rotation and dilation.</em>
Dilation is the increase or decrease in the size of a figure by a factor k. If a figure is dilated to produce an image, they are similar, hence the ratio of the corresponding sides are proportional.
The length of the side between the vertices A′ and B′ is 16/7 units.

The fraction of the image in blue with respect to the <em>entire</em> hexagon is .
Initially we proceed to create auxiliar constructions , represented by red line segments, to re-define the hexagon as a sum of standard figures. According to the figure, we find two types of triangles (type-1 and type-2), and the following relationship between the two types:
(1)
Where:
- Area of a type-1 triangle.
- Area of a type-2 triangle.
The formulae for the area of the shaded region () and the <em>entire</em> hexagon (
