Geometry

This chapter explains polygons and their types in detail. It describes the notion of simple closed figures and diagonals. It briefs on convex and concave polygons, regular polygons and their angles. We will learn how to find the angle sum of any polygons.

This chapter sheds light on the perimeter and area of various 2-D figures. We will learn how to find the area and perimeter of a square, rectangle and triangle. It also discusses the applications of perimeter and area.

This chapter describes the concept of symmetry in detail. It highlights reflection symmetry and explains geometrical patterns based on this symmetry. It also discusses the different views of a solid and briefs on them.

This chapter discusses the 3-D and 2-D solid shapes. It discusses different shapes, such as the polyhedron, prism, pyramid, etc. It also illustrates Euler's relation with the help of the examples discussed here.

This chapter enhances our knowledge regarding various geometrical figures. These include rectangle, square, triangle, and circle. It provides information on some solid shapes. We will also learn how to trace solid shapes on a paper.
