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.
