Final answer:
To determine which term does not describe the figure, one needs to consider the definition of each term. If the figure is a regular hexagon, the term 'concave' would not apply, as a regular hexagon is always convex with equal sides and angles.
Step-by-step explanation:
The term that does NOT describe the figure in question would depend on the properties of the figure itself, which are not provided in the provided information. However, I can explain the terms given:
- A concave figure is one where at least one interior angle is greater than 180 degrees, causing a 'caved-in' appearance.
- A hexagon is a six-sided polygon.
- A polygon is a closed figure with sides made up of line segments.
- A regular polygon is one where all sides and angles are equal.
If a figure is described as a hexagon and regular, it means it has six equal sides and six equal angles, ruling out the term 'concave' for this particular figure. Similarly, if it's a hexagon, it is by definition a polygon. The term 'concave' typically does not apply if the figure is a regular hexagon, as regular polygons are always convex.
