**Choose the correct answer from the given four options (1 to 12) :**

**Question 1.**

**The points A (9, 0), B (9, 6), C ( – 9, 6) and D ( – 9, 0) are the vertices of a**

**(a) rectangle**

**(b) square**

**(c) rhombus**

**(d) trapezium**

**Solution:**

A (9, 0), B (9, 6), C (-9, 6), D (-9, 0)

AB² = (x_{2} – x_{1})² + (y_{2} – y_{1})²

**Question 2.**

**The mid-point of the line segment joining the points A ( – 2, 8) and B ( – 6, – 4) is**

**(a) ( – 4, – 6)**

**(b) (2, 6)**

**(c) ( – 4, 2)**

**(d) (4, 2)**

**Solution:**

Mid-point of the line segment joining the points A (-2, 8), B (-6, -4)

**Question 3.**

**If \(P\left( \frac { a }{ 3 } ,4 \right) \) segment joining the points Q ( – 6, 5) and R ( – 2, 3), then the value of a is**

**(a) – 4**

**(b) – 6**

**(c) 12**

**(d) – 12**

**Solution:**

\(P\left( \frac { a }{ 3 } ,4 \right) \) is mid-point of the line segment

joining the points Q (-6, 5) and R (-2, 3)

**Question 4.**

**If the end points of a diameter of a circle are A ( – 2, 3) and B (4, – 5), then the coordinates of its centre are**

**(a) (2, – 2)**

**(b) (1, – 1)**

**(c) ( – 1, 1)**

**(d) ( – 2, 2)**

**Solution:**

End points of a diameter of a circle are (-2, 3) and B (4,-5)

then co-ordinates of the centre of the circle

= \(\left( \frac { -2+4 }{ 2 } ,\frac { 3-5 }{ 2 } \right) or\left( \frac { 2 }{ 2 } ,\frac { -2 }{ 2 } \right) \)

= (1, -1) (b)

**Question 5.**

**If one end of a diameter of a circle is (2, 3) and the centre is ( – 2, 5), then the other end is**

**(a) ( – 6, 7)**

**(b) (6, – 7)**

**(c) (0, 8)**

**(d) (0, 4)**

**Solution:**

One end of a diameter of a circle is (2, 3) and centre is (-2, 5)

Let (x, y) be the other end of the diameter

**Question 6.**

**If the mid-point of the line segment joining the points P (a, b – 2) and Q ( – 2, 4) is R (2, – 3), then the values of a and b are**

**(a) a = 4, b = – 5**

**(b) a = 6, b = 8**

**(c) a = 6, b = – 8**

**(d) a = – 6, b = 8**

**Solution:**

the mid-point of the line segment joining the

points P (a, b – 2) and Q (-2, 4) is R (2, -3)

**Question 7.**

**The point which lies on the perpendicular bisector of the line segment joining the points A ( – 2, – 5) and B (2, 5) is**

**(a) (0, 0)**

**(b) (0, 2)**

**(c) (2, 0)**

**(d) ( – 2, 0)**

**Solution:**

the line segment joining the points A (-2, -5) and B (2, -5), has mid-point

= \(\left( \frac { -2+2 }{ 2 } ,\frac { -5+5 }{ 2 } \right) \) = (0, 0)

(0, 0) lies on the perpendicular bisector of AB. (a)

**Question 8.**

**The coordinates of the point which is equidistant from the three vertices of ∆AOB (shown in the given figure) are**

**(a) (x, y)**

**(b) (y, x)**

**(c) \(\left( \frac { x }{ 2 } ,\frac { y }{ 2 } \right) \)**

**(d) \(\left( \frac { y }{ 2 } ,\frac { x }{ 2 } \right) \)**

**Solution:**

In the given figure, vertices of a ∆OAB are (0, 0), (0, 2y) and (2x, 0)

The point which is equidistant from O, A and B is the mid-point of AB.

∴ Coordinates are \(\left( \frac { 0+2x }{ 2 } ,\frac { 2y+0 }{ 2 } \right) \) or (x, y) (a)

**Question 9.**

**The fourth vertex D of a parallelogram ABCD whose three vertices are A ( – 2, 3), B (6, 7) and C (8, 3) is**

**(a) (0, 1)**

**(b) (0, – 1)**

**(c) ( – 1, 0)**

**(d) (1, 0)**

**Solution:**

ABCD is a ||gm whose vertices A (-2, 3), B (6, 7) and C (8, 3).

The fourth vertex D will be the point on which diagonals AC and BD

bisect each other at O.

**Question 10.**

**A line intersects the y-axis and x-axis at the points P and Q respectively. If (2, – 5) is the mid-point of PQ, then the coordinates of P and Q are, respectively**

**(a) (0, – 5) and (2, 0)**

**(b) (0, 10) and ( – 4, 0)**

**(c) (0, 4) and ( – 10, 0)**

**(d) (0, – 10) and (4, 0)**

**Solution:**

A line intersects y-axis at P and x-axis a Q.

R (2, -5) is the mid-point

**Question 11.**

**(d) IVth quadrant**

**Solution:**

A point divides line segment joining the points

A (7, -6) and B (3, 4) in the ratio 1 : 2 internally.

Let (x, y) divides it in the ratio 1 : 2

**Question 12.**
