Curriculum-aligned Mathematics questions for Class 9 under CBSE. Shortlist topics, practice at your pace, and make every answer count.
Consider two lines l1 and l2 that intersect at point P forming angles of 40° and 140° at that point. Verify whether these angles satisfy the property of vertically opposite angles. Then, if a transversal line cuts through these two lines forming alternate interior angles of 60° and x°, find the value of x. Explain your reasoning and show all calculations involved.
In the Cartesian coordinate system, plot the points A(3, 4), B(-2, 5), C(-3, -1), and D(1, -3). Identify the quadrant in which each point lies and explain how the signs of the coordinates determine the position of the points in relation to the axes. Additionally, calculate the distance between points A and B using the distance formula and illustrate your working steps clearly.
Plot the point (-2, 5) and state which quadrant it belongs to.
Describe the characteristics of the first quadrant in the Cartesian coordinate system.
Plot the point (4, -3) on a Cartesian plane and identify its coordinates.
Define intersecting lines and give an example of how they are different from parallel lines.
In a transversal intersecting two parallel lines, what are the alternate interior angles? Explain.
Explain how to calculate the area of two parallelograms on the same base and between the same parallels.
If two triangles have the same base and height, what can you say about their areas? Justify your answer.
Prove that if two figures are on the same base and between the same parallels, then their areas are equal.
In a triangle, what is the sum of all interior angles?
