FAQs on Classification of Polygons based on Number of sides Video Lecture - Advance Learner Course: Mathematics (Maths) Class 7

1. What is a polygon?
Ans. A polygon is a closed two-dimensional figure formed by straight lines called sides. It consists of vertices (corners) and edges connecting these vertices. The sides of a polygon do not intersect each other.
2. How are polygons classified based on the number of sides they have?
Ans. Polygons are classified based on the number of sides they have. Some common classifications include: - 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 polygons have an infinite number of sides?
Ans. No, polygons cannot have an infinite number of sides. By definition, polygons are closed figures with a finite number of sides. The sides of a polygon are always straight lines, and they must meet at their endpoints to form vertices.
4. Are all sides of a polygon required to be of equal length?
Ans. No, all sides of a polygon are not required to be of equal length. A polygon can have sides of different lengths. However, there are specific types of polygons, such as equilateral polygons, where all sides are of equal length.
5. Are polygons limited to two-dimensional shapes only?
Ans. Yes, polygons are limited to two-dimensional shapes. They exist on a flat plane and have length and width, but not depth. Polygons are commonly encountered in geometry, where they are studied and classified based on their properties and number of sides.
