Answer:
C. an irregular concave heptagon
Explanation:
Before we begin, we should define the terms used in the choices given:
1- Heptagon: It is the polygon that has 7 sides
2- Regular heptagon: It is a 7-sided polygon in which all sides are equal and all angles are equal
3- Irregular heptagon: It is a 7-sided polygon in which neither the sides nor the angles are equal
4- Concave heptagon: It is a 7-sided polygon in which one or more of its angles are more than 180°
5- Convex heptagon: It is a 7-sided polygon in which all its angles are less than 180°
6- Complex heptagon: It is a 7-sided polygon whose dimensions are in the complex plane
Now, let's check the given diagram:
It is a 7-sided polygon, therefore, it is a heptagon
It's sides as well as its angles are not equal, therefore, it is an irregular heptagon
It has interior angles measuring more than 180°, therefore, it is a concave heptagon
Its dimensions are not in the complex plane, therefore, it is not a complex polygon
Based on the above, the best choice is:
C. an irregular concave heptagon
Hope this helps :)
