THE DALY COLLEGE, INDORE ASSIGNMENT MATHEMATICS (Class - IX) Solve the equation 2x + 1 = x 3, and represent the solution(s) on (i) the number line, (ii) the Cartesian plane. 2. In a quadrilateral ABCD, AO and BO are the bisectors of A and B respectively. Prove that AOB = 1 ( C + D). 2

4 3. Construct a triangle ABC in which AB = 5.8 cm, BC + CA = 8.4 cm and B = Construct a triangle ABC in which BC = 3.8 cm, AB + CA = 6.8 cm and B = Construct a triangle ABC in which base AB = 5 cm, AC BC = 2.5 cm and A = Construct a triangle ABC in which BC = 5.7 cm, AB CA = 3 cm and B = Using ruler and compasses only, construct a ABC from the following data: AB + BC + CA = 12 cm, B = 45 0 C = Construct a triangle XYZ in which Y = 30 0, Z = 90 0 and XY + YZ + ZX = 11 cm. 9. The angles of a quadrilateral are in the ratio 3 : 5 : 9 : 13. Find all the angles of the quadrilateral. 10. Draw a graph of the equation : (i) y = 3 (ii) 2y + 3 = A three wheeler scooter charges Rs 15 for first kilometer and Rs 8 each for every subsequent km. For a distance of x km and amount of Rs y is paid. Write the linear equation representing the above information. 12. Let ABC be an isosceles triangle with AB = AC and let D, E, F be the midpoints of BC, CA and AB respectively. Show that AD FE and AD is bisected by FE. 13. In the given figure, AD and BE are medians of ABC and BE DF. Prove that CF = 1 4 AC. A E F B D C 14. In ABC, AD is the median through A and E is the midpoint of AD. BE produced meets AC in F (Figure). Prove that AF = 1 3 AC. A E F K B D C

5 15. Show that the quadrilateral ABCD formed by joining the mid-points of the sides of a square, is also a square. 16. If the Diagonals AC, BD of a quadrilateral ABCD, intersect at O, and separate the quadrilateral into four triangles of equal area, show that quadrilateral ABCD is a parallelogram. 17. In ABC, D is the mid-point of AB. P is any point of BC. CQ PD meets AB in Q. Show that ar ( BPQ) = 1 ar( ABC) ABC is a triangle in which D is the mid-point of BC and E is the mid-point of AD. Prove that area of BED = 1 area of ABC Find the value of k, if x = 1, y = 1 is a solution of the equation 2x + 3y = k. 20. If x = 1, y = 2 is a solution of the equation a 2 x + ay = 3, then find the value of a. 21. If x = 2k 1 and y = k is a solution of the equation 3x 5y 7 = 0, find the value of k. 22. Draw the graph of the equation y x = Draw the graph of the equation 2x + y = Give the equations of two lines passing through (3, 12). How many more such lines are there, and why? 25. A lending library has a fixed charge for the first three days and an additional charge for each day thereafter. Aarushi paid Rs27 for a book kept for seven days. If fixed charges are Rs x and per day charges are Rs y. Write the linear equation representing the above information.
