Mathematics

Coordinate Geometry

In this chapter, we review concepts of geometry and graphs of linear equations for the better understanding of coordinate geometry. We learn formula of distance between two points, collinear points, section formula, centroid and area of a triangle.

This topic covers concepts such as coordinate system, coordinate system in 2D, coordinate axes in 2D, X-axis of coordinate system in 2D, Y-axis of coordinate system in 2D, etc.

Introduction to Coordinate geometry

This topic covers concepts such as distance of a point from coordinate axes, equations of lines parallel to the X-axis, etc.

Parallel Lines along Coordinate Axes

This topic covers concepts such as graph of a linear equation in two variables, equations of lines passing through the origin, etc.

This chapter describes the terms related to a cone and gives the formula to find surface area and volume. It also explains the surface area of a sphere and includes some solved examples to explain the application of these formulas.

Surface Area and Volume

In this chapter, we will learn about the circle and its components. It explores the properties of a chord and congruent chords. It also explains the method to construct the incircle and the circumcircle of a triangle.

Circle

This chapter discusses the properties of the rectangle, rhombus, and square. It includes a test to check if the given figure is a parallelogram or not, and explores the theorem of mid-points of two sides of a triangle

Quadrilaterals

This chapter explains three methods of the construction of a triangle. It&nbsp;explores the statement of the perpendicular bisector theorem and gives some exercises and examples to teach us about the construction of the triangles.

Constructions of Triangles

This chapter explores theorems on triangles and properties of exterior angles of a triangle. We will learn about similar triangles and similarity of triangles. It describes the properties of inequalities of sides and angles of triangle.

Triangles

This chapter explores the properties of parallel lines and includes the theorems related to parallel lines. It describes some tests to verify whether the two given lines are parallel or not.

Parallel Lines

This chapter focuses on the concepts related to a line segment. It defines the coordinates, distance, and midpoint of the line segment. It covers the properties of congruent line segments and explores the conditional statements with their converse.
