A half of a hexagon is commonly referred to as a ‘trapezoid’ or ‘trapezium,’ depending on the context and regional terminology. However, in geometric terms, when you split a regular hexagon exactly in half, you create two congruent trapezoids, as each half has a pair of parallel sides and two non-parallel sides.
To elaborate, a regular hexagon consists of six equal-length sides and angles. If you draw a line through the center of the hexagon, dividing it into two equal parts, each part retains the hexagonal shape’s symmetrical properties, but as a two-dimensional shape, it resembles a trapezoid. This is because each half has a pair of sides that are parallel—one from the original top side of the hexagon and one from the bottom side.
In summary, while ‘trapezoid’ is commonly used to describe this shape, the exact terminology may vary, but it’s important to remember that splitting a hexagon gives you a shape that matches the characteristics of trapezoids.
