FAQs on Classification of Polygons based on Number of Sides-2 Video Lecture - Mathematics (Maths) Class 8

1. What is a polygon?
A polygon is a two-dimensional shape with straight sides that are connected to form a closed figure. It has three or more sides, and each side intersects at its endpoints.
2. How are polygons classified based on the number of sides?
Polygons are classified based on the number of sides they have. Here are some common classifications: - Triangle: A polygon with three sides. - Quadrilateral: A polygon with four sides. - Pentagon: A polygon with five sides. - Hexagon: A polygon with six sides. - Heptagon: A polygon with seven sides. - Octagon: A polygon with eight sides. - Nonagon: A polygon with nine sides. - Decagon: A polygon with ten sides.
3. Can a polygon have an infinite number of sides?
No, a polygon cannot have an infinite number of sides. A polygon is a closed figure, and by definition, it must have a finite number of sides. Each side must also be a straight line segment.
4. How can you determine the number of sides of a polygon?
To determine the number of sides of a polygon, you can count the number of line segments that form its boundary. Each line segment represents a side of the polygon. For example, if you count five line segments, the polygon has five sides and is called a pentagon.
5. Are there any polygons with less than three sides?
No, a polygon must have at least three sides. A figure with fewer than three sides cannot be considered a polygon. A polygon needs three sides to form a closed figure and to have a defined interior and exterior.
