A polygon can be classified based on several characteristics, including the number of sides it has, the types of angles it contains, and the lengths of its sides. The primary classifications of polygons are as follows:
-
By the number of sides:
- Triangle: 3 sides
- Quadrilateral: 4 sides
- Pentagon: 5 sides
- Hexagon: 6 sides
- Heptagon: 7 sides
- Octagon: 8 sides
- Nonagon: 9 sides
- Decagon: 10 sides
-
By the types of angles:
- Equiangular: All angles are equal.
- Convex: All interior angles are less than 180 degrees.
- Concave: At least one interior angle is greater than 180 degrees.
-
By the lengths of sides:
- Regular: All sides and angles are congruent.
- Irregular: Sides and/or angles are not congruent.
These classifications help in understanding the properties and characteristics of different polygons.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
