Coordinate Geometry
निर्देशांक ज्यामिति
In this Class 9 Mathematics chapter, students learn how the Cartesian plane represents the position of points using ordered pairs. They explore the x-axis, y-axis, origin, and four quadrants, understand how signs affect coordinates, and plot points accurately on a graph. The chapter also develops skills for reading coordinates, identifying the quadrant or axis containing a point, and describing locations clearly through numerical and visual representation.
1Cartesian plane
कार्तीय तल
In Class 9 Mathematics, the Cartesian plane introduces students to the graphical language of Coordinate Geometry. They learn how two perpendicular number lines—the x-axis and y-axis—meet at the origin to form a coordinate system, and how the plane is divided into four quadrants. Students read and write ordered pairs, identify the coordinates of points, plot them accurately, and use the signs of coordinates to determine a point’s position. These skills help them represent geometric relationships clearly on a graph.
0 questionsCoordinates of a point
किसी बिंदु के निर्देशांक
In this Class 9 Mathematics topic from Coordinate Geometry, students learn how a point is identified on the Cartesian plane using an ordered pair of numbers. They understand the x-axis, y-axis, origin, and the role of the horizontal and vertical coordinates. Students practise reading coordinates from a graph, plotting points accurately, and recognising the quadrant or axis on which a point lies. These skills build a clear foundation for representing and interpreting geometric information visually.
0 questionsDistance between two points
दो बिंदुओं के बीच की दूरी
In Class 9 Mathematics, this Coordinate Geometry topic teaches students how to find the distance between two points on the Cartesian plane. They learn to represent points using ordered pairs, compare their horizontal and vertical differences, and apply the distance formula √[(x₂−x₁)² + (y₂−y₁)²]. The concept is connected to the Pythagorean theorem and helps students solve geometric problems involving points, line segments, and coordinate-based figures.
0 questionsMidpoint of a line segment
रेखाखंड का मध्यबिंदु
In this Class 9 Mathematics topic from Coordinate Geometry, students learn how to find the midpoint of a line segment when the coordinates of its endpoints are known. They use the midpoint formula by averaging the x-coordinates and the y-coordinates separately, understand why the resulting point lies halfway between the endpoints, and apply the method to verify, compare, and solve coordinate-based geometric problems accurately.
0 questionsCollinearity
बिंदुओं की समरेखीयता
In this Class 9 Mathematics topic from Coordinate Geometry, students learn the meaning of collinearity: when two or more points lie on the same straight line. They practise locating and plotting points on the Cartesian plane, observing their alignment, and using coordinate-based methods to decide whether a set of points is collinear. The topic strengthens understanding of ordered pairs, axes, straight lines, and geometric relationships, while developing accuracy in reading and interpreting coordinate diagrams.
0 questionsRight-angled triangle using coordinates
निर्देशांकों द्वारा समकोण त्रिभुज
In this Class 9 Mathematics topic from Coordinate Geometry, students learn how to represent the vertices of a triangle as ordered pairs and plot them on the Cartesian plane. They examine the positions and coordinate differences of the points to identify when two sides are perpendicular and the triangle is right-angled. The topic develops accuracy in plotting, reading coordinates, comparing horizontal and vertical changes, and explaining geometric relationships using a diagram and clear mathematical reasoning.
0 questionsCartesian system, quadrants, and axes
कार्तीय निर्देशांक तंत्र, चतुर्थांश और अक्ष
In Class 9 Mathematics, this topic from Coordinate Geometry introduces the Cartesian plane as a way to locate and describe points precisely. Students learn about the x-axis, y-axis, origin, coordinate pairs, and the four quadrants. They understand how the signs of the coordinates change from one quadrant to another, plot ordered pairs on a graph, and read the coordinates of given points. These ideas build a clear foundation for representing geometric relationships using numbers and diagrams.
0 questionsPlotting coordinates in a plane when given coordinates
दिए गए निर्देशांकों से समतल पर बिंदु अंकित करना
In this Class 9 Mathematics topic from Coordinate Geometry, students learn how to plot a point on the Cartesian plane when its coordinates are given. They identify the x-coordinate and y-coordinate, locate the correct positions on the horizontal and vertical axes, and mark points accurately in the appropriate quadrant or on an axis. The topic also builds understanding of ordered pairs, the origin, coordinate axes, and how signs indicate the position of a point.
