Today my maths exam was over. I am giving some important questions that came in our exam.
If anyone's exam is yet to be start can revise. THERE ARE DIFFERENT SETS ISSUED BY BOARD THEREFORE THERE MIGHT BE DIFFERENT QUESTIONS SET IN YOUR SCHOOL.
HOWEVER, you can revise from this paper. I am sorry because i could not type some questions which included roots,etc because their signs are not present on keyboard.
IT IS NOT A SAMPLE PAPER.
Q1..in a right angle triangle, if one acute angle is half the other, then find the smallest angle.
Q2. in which quadrant does the point (-1,2) lie?
Q3. factorise:-4a square -9b square - 2a -3b.
Q4. define the terms and also draw them:
1) parallel lines 2) perpendicular lines
Q5. are the points (0,5) and (5,0) lie in the same quadrant? give reason for your answer.
Q6. the sides of triangle are 9cm, 12cm and 15cm. find its area.
Q7. if x=2 and x=0 are the zeroes of polynomial f(x) = 2x cube - 5x square +ax +b,then find the values of a and b.
Q8. a point 0 is taken inside an equilateral four sided figure ABCD such that its distance from the angular points D and B are equal. Show that AO and OC are in one and the same straight line.
Q9. prove that "angles opposite to equal sides of an isosceles triangle are equal.
Q10. in a rectangular field of dimensions 50m X 30m a triangular park is constructed. If the dimensions of the park is 14m, 15m and 13m. Find the area of remaining field.
Q11. calculate the area f parallegoram whose adjacent sides are 20cm, 34cm and diagonal is 42cm.
Q12. if p(x)=x cube -4x square +x + 6, then show that p(3) = 0 and hence factorise p(x)
Q13. (a square - 2a)whole square - 23(a square - 2a) +120
Q14. simplify (a +b)whole cube + (a-b)whole cube +6a(a square - b square)
Q15. if a transversal intersects two lines such that the bisectors of a pair of corresponding angles are parallel, then prove that two lines are parallel.
Q16. if two lines intersect, prove that their vertically opposite angles are equal.
Q17. Prove that any two sides of a triangle are together greater than twice the median drawn to the third side.
