MATHEMATICS Class: IX English Medium

(Max. Marks :

Name of the Student:.

I. Answer the following questions.

1. Name the three undefined terms in geometry.

1 Point,line,plane

2. Write the complementary and supplementary angles of 70°.

2. Complementary angle = 90-70 = 20

Supplementary angle = 180-70-110

3. The linear equation y = 3x + 5 has

A) A unique solution

C) Only two solutions

B) No solution

D) Infinitely many solutions

Answer – D

6. Find the value of ‘k’, if x = 2, y = 1 is a solution of the equation 2x + 3y = k.

Solve the following problem.

6. 2x+3y=k

If x=2,y = 1

K=?

2(2) + 3(1)=k

4+3= k

7=k

K=7

4. What are the names of the vertical and the horizontal lines drawn to determine the position of any point in the Cartesian plane and also name the intersecting point of two lines?

II. Solve the following problems.

4. Horizontal line is called x-axis

Vertical line is called y-axis Origin

5. Give the geometric representations of y = 3 as an equation

a) In one variable

b) In two variables

. (i) y = 3

(ii) y=3

⇒0x+y=3

⇒0x+y-3=0

7. Prove that equilateral triangle can be constructed on any given line segment.

IV. Solve the following problem.

Given-In AABC one side is x cm

Construction – Draw a AABC using following steps –

1) Draw a line segment AB = x cm

2) Using compass point A is centre and radius x cm draw a arc

3) Using compass assume point B is centre and same radius draw a arc.

4) Both are is cut this point which name is C

5) Thus we draw a equilateral traingle

8. a) Find four solutions for the linear equation 2x + y = 7.

2×2=4

1×4=4

1×8=8

(Or)

b) Plot the points P(0, -4) and Q(0,4) on the graph paper. Now, plot the points R and S so that APQR and APQS are isosceles. How many isosceles triangles can be formed?

8. A) 2x + y = 7

Y = 7-2x

IfX=1

Y=7-2(1)

Y = 7-2

Y=5(1,5)

If X = 2

Y=7-2(2)

Y=7-4

Y=3(2.3)

If X = 3

Y=7-2(3)

Y=7-6

Y=1(3.1)

If X= 4

Y=7-2(4)

Y = 7-8

Y=-1 (4-1)

B)Step-by-step explanation: As given in the question, the points P(0, -4) and Q(0,4) are plotted on a graph paper in the attached file.

We also take the point R as (5, 0) and the point S as (-5, 0).

These are plotted in the same graph.

We can see clearly that APQR and APSR are isosceles triangles, where

PR=QR, PS = QS. Hence completed.

Q(0,4)
