Chapter 15-Understanding Shapes-I (Polygons)


Introduction to Polygons

Chapter 15 focuses on Understanding Shapes – I (Polygons), which helps students explore various two-dimensional figures and their properties. Polygons are closed plane figures formed by straight line segments. This chapter forms the base for geometry in higher classes.

Key Concepts Covered

This chapter includes:

  • Definition and classification of polygons

  • Regular and irregular polygons

  • Convex and concave polygons

  • Diagonals and their properties

  • Sum of interior and exterior angles

Each section in RD Sharma provides multiple examples and practice exercises that simplify geometric understanding.

Learning Through Visual Understanding

Students learn how to identify different polygons such as triangles, quadrilaterals, pentagons, hexagons, and octagons. Through diagrams and explanations, the chapter enhances visual and spatial reasoning.

Importance in Geometry

Understanding polygons is vital for studying further geometric topics like quadrilaterals, symmetry, and mensuration. RD Sharma Solutions for class 8 Maths exercises make students comfortable in identifying properties and solving angle-based questions.
