You can study this concept in-depth in the RS Aggarwal solutions class 8, it provides you with a better understanding of the topics and helps you to score more marks in your exams.

2. What are interior and exterior angles of polygons described in RS Aggarwal Solutions Class 8 Chapter-14 Polygons (Ex 14B) Exercise 14?

RS Aggarwal class 8 maths chapter 14 polygon gives detailed answers to all the concepts and it is written in simple language to help students to understand it and learn it easily. The angles which are inside the polygon are called interior angles and the angles that are outside the polygon are called exterior angles. The sum of the interior angles of a polygon is given by (n−2) × 180°, where ‘n’ sides. You can get a complete understanding of the topic with expert guidance from excellent and experienced teachers of Vedantu.

3. What are the different types of polygons explained in RS Aggarwal Solutions Class 8 Chapter-14 Polygons (Ex 14B) Exercise 14?

There are 4 types of a polygon:

• Regular polygons- polygons with all the equal interior angles are known as regular polygons.

• Irregular polygons- polygons with different interior angles at each side are called irregular polygons.

• Convex polygon: when the sum of all the interior angles is less than 180 degrees then it is called a convex polygon. For example, an equilateral triangle.

• Concave polygon- when the sum of all the interior angles of a polygon is more than 180 degrees, then it is known as a concave polygon.

4. What type of questions are covered in RS Aggarwal Solutions Class 8 Chapter-14 Polygons (Ex 14B) Exercise 14?
