Geometry

This chapter explains the terms associated with quadrilaterals. We will learn about the angle sum and exterior angle sum property of the quadrilaterals. It also briefly discusses rhombus, parallelogram, square and some other shapes.

This chapter explains the construction of quadrilaterals using five different measurements of quadrilaterals. It also describes the construction process of rectangular, square, parallelogram and rhombus shapes.

A circle is formed by all points in the same plane at equal distances from a point called centre. This chapter discusses the interior, exterior and circular regions of the circle. It also describes a concentric circle and the various terms associated with a circle.

This chapter explains the symmetry of a point, line and the method of finding the line of symmetry for different symmetrical objects.The concepts of rotational symmetry and its the order are also covered here in detail.

This chapter explains the various terms associated with solid shapes. It describes the method of drawing the nets of a cuboid, cube, pyramid, cylinder and cone. It also discusses the construction of 3-D and 2-D shapes and the verification of Euler’s formula.
