The number line is a graphical representation of the real number system. It is a straight line that extends infinitely in both directions. The numbers are marked on the line to depict their relative values and order.


A bar graph is used to represent categorical data using rectangular bars. The length of each bar is proportional to the frequency or value it represents. It is often used to compare data across different categories.


A line graph is a graphical representation of data that uses lines to connect individual data points. It is commonly used to show the trend or relationship between two variables over a continuous interval.


A pie chart is a circular graph divided into sectors that represent different categories or parts of a whole. The size of each sector is proportional to the quantity it represents. It is useful for displaying data that can be divided into distinct categories.


A histogram is a graphical representation of data that uses bars to display the frequency distribution of a continuous variable. The bars are drawn adjacent to each other, and the area of each bar represents the frequency or relative frequency of the data.


Coordinate geometry involves the study of geometric figures using a coordinate system. It includes plotting points on a Cartesian plane, finding the distance between points, and determining equations of lines and curves.


A circle is a closed curve formed by all points equidistant from a fixed center point. It is represented by a round shape with a center point and a radius. Circles are used to solve problems related to the properties of circles, tangents, and chords.


Triangles are three-sided polygons that have various properties and classifications. Important triangles include equilateral, isosceles, scalene, and right-angled triangles. Diagrams of triangles are often used to solve problems involving angles, sides, and congruence.


Quadrilaterals are four-sided polygons with diverse properties and classifications, such as squares, rectangles, parallelograms, and trapeziums. Diagrams of quadrilaterals are essential for understanding their properties, angles, diagonals, and area.


Graphs of linear equations are straight lines that represent the relationship between two variables. They are used to solve problems involving simultaneous linear equations, slope-intercept form, and the graphical interpretation of equations.

These diagrams and graphs are crucial in CBSE Class 10 Mathematics as they help students visualize and understand various mathematical concepts, relationships, and data representations.
