Final answer:
A triangle has 3 sides, a quadrilateral has 4 sides, a pentagon has 5 sides, and a hexagon has 6 sides. None of these polygons are equilateral, equiangular, or regular.
Step-by-step explanation:
The question is asking to classify the given polygon by its number of sides and determine if it is equilateral, equiangular, regular, or NONE. Let's go through each option:
- a) Triangle: A triangle has 3 sides, so this polygon falls into the category of a triangle. It is also possible for a triangle to be equilateral if all three sides are equal in length, equiangular if all three angles are equal, and regular if it is both equilateral and equiangular.
- b) Quadrilateral: A quadrilateral has 4 sides, so this polygon falls into the category of a quadrilateral. It can be equilateral if all four sides are equal in length, equiangular if all four angles are equal, and regular if it is both equilateral and equiangular.
- c) Pentagon: A pentagon has 5 sides, so this polygon falls into the category of a pentagon. It cannot be equilateral, equiangular, or regular as it does not satisfy the conditions for any of those classifications.
- d) Hexagon: A hexagon has 6 sides, so this polygon falls into the category of a hexagon. It cannot be equilateral, equiangular, or regular as it does not satisfy the conditions for any of those classifications.
Therefore, the classifications for each polygon are: a) Triangle, b) Quadrilateral, c) Pentagon, d) Hexagon II. As for the second part of the question, none of these polygons are equilateral, equiangular, or regular.
