The shape that has 3 pairs of parallel sides is a hexagon.
A hexagon is a polygon with six sides and six angles. In a specific type of hexagon known as a parallelo-hexagon, it can be structured so that it has three pairs of parallel sides. This means that there are sets of opposite sides that are equal in length and parallel to each other. This property is quite useful in various fields, especially in geometry, engineering, and architecture, where understanding the relationships between different sides and angles is crucial.
