Geometry

Through this chapter, we will gain knowledge about the point, line and plane by learning how to represent the line and points in a plane. We will also learn about the concept of line segments with the diagrammatic illustrations.

This chapter deals with the concepts of angles. Here, we will learn about the complementary, supplementary and vertically opposite angles. We will also study the adjacent and linear pair of angles with examples and exercises.

This chapter discusses the properties of parallel lines and transversal lines. Here, we will learn about corresponding, alternate interior, alternate exterior and consecutive interior angles. It also explains the two parallel lines cut by a transversal.

In this chapter, we will learn how to draw a parallel line to a given line passing through a given point. It also teaches us how to construct the geometries with a set square and ruler with the aid of geometric illustrations.

In this chapter, we will learn how to name and classify triangles by considering the length of their sides and angle measurements. It discusses the median and altitudes of triangles. We will also learn to construct a triangle.

This chapter deals with the property of congruence in distinct figures by discussing the figures that have the same shape. It talks about congruent figures with examples. It discusses the conditions for congruency of two triangles.

This chapter discusses the concept of polygons, along with their geometric illustrations. It classifies the polygons into convex, regular and concave polygons. We will also study the angle property of a polygon.

In this chapter, we will learn about the quadrilaterals along with its types. It discusses the properties and constructions of parallelogram, rectangle, square, kite, rhombus and trapezium with the examples.

This chapter comprises a study of the circles with the interior and exterior of a circle. It explains the chord, diameter, secant, tangent and arc of a circle. It also briefs us on concentric circles with the sector and segments of the circle.

This chapter deals with the concept of symmetry. We will learn about the reflection and rotational symmetries, their conditions and properties with the help of examples and exercises. It comprises the figures with their symmetries.
