## FAQs on RD Sharma Class 8 Maths Solutions Chapter 15 - Understanding Shapes I (Polygons)

1. What is a curve?

A linear or line which deviates from its shape for some or the whole part of its length is a curve. A closed curve is a curve that completely encloses the area. It is drawn smoothly on the surface with subtle bends on the sides. A circle is an example of a curved surface. Students of Class 8 can learn more about polygons from the Class 8 RD Sharma Textbook Solutions Chapter 15 - Understanding shapes (Polygons) available on the Vedantu.

2. What is a polygon?

The term “Polygon” can be divided into “poly” and “gon”. Poly means many and gon means sides. Hence, a polygon is a figure with many sides. A polygon is a closed figure drawn in a flat shape, which is made of line segments that join each other to make it a closed figure. Students must understand the concepts given in the Class 8 RD Sharma Textbook Solutions chapter 15 - Understanding shapes (Polygons). They can refer to the solutions to get a quick understanding about the polygons.

3. Are all curves considered polygons?

A polygon is a simple curve but all curves are not polygons because a polygon has three or more line segments joining each other. For example, square and rectangle are four sided figures.They are polygons. They are not curved but they are called polygons. A circle is a curved surface and it is not a polygon. For more information on curved surfaces and polygons students must understand the concepts given in the Chapter 15 of Class 8 Maths.

4. Is a circle polygon?

As the circle is formed by a curve and does not have any line segments, it misses the essential conditions to be a polygon. Hence, a circle can not be considered a polygon. A polygon is a plane figure with three or more line segments joining each other at endpoints. For example, a pentagon, hexagon, a rectangle, a rhombus, are all different polygons. Students must solve the Class 8 RD Sharma textbook solutions Chapter 15 to understand the concepts of polygons.

5. What are the examples of a polygon?

Triangle, quadrilateral, hemispheres are some of the examples of a polygon. The classification of polygons is based on no. of sides and vertices, a polygon with four sides is called a quadrilateral. A polygon is a plane figure with more than two line segments joining at the endpoint. On the other hand, polygons are classified into concave and convex polygons based on their interior angles. The interior angles of a convex polygon is less than or equal to 180.
