ML Aggarwal Mid Point Theorem MCQs Class 9 ICSE Maths Solutions Ch-11

Question 1. In a ∆ABC, AB = 3 cm, BC = 4 cm and CA = 5 cm. If D and E are mid-points of AB and BC respectively, then the length of DE is

(a) 1.5 cm
(b) 2 cm
(c) 2.5 cm
(d) 3.5 cm

Answer : (c) 2.5 cm is correct

Hint : In ∆ABC, D and E are the mid-points of sides AB and BC

In a ∆ABC, AB = 3 cm, BC = 4 cm and CA = 5 cm. IfD and E are mid-points of AB and BC respectively, then the length of DE is

DE = 1/2 Ac

But AC = 5 cm

DE = 1/2 x 5

= 5/2 cm

= 2.5 cm

Question 2. In the given figure, ABCD is a rectangle in which AB = 6 cm and AD = 8 cm. If P and Q are mid-points of the sides BC and CD respectively, then the length of PQ is

(a) 7 cm
(b) 5 cm
(c) 4 cm
(d) 3 cm

Answer : (b) 5 cm is correct

Hint :  In the figure,   ABCD is a rectangle AB = 6 cm AD = 8 cm

P and Q are mid-points of BC and CD

PQ = 1/2 BD

But BD = Mid point therom ml class 9 chapter 11 img 15

In the given figure, ABCD is a rectangle in which AB = 6 cm and AD = 8 cm. If P and Q are mid-points of the sides BC and CD respectively, then the length of PQ is

Question 3. D and E are mid-points of the sides AB and AC of ∆ABC and O is any point on the side BC. O is joined to A. If P and Q are mid-points of OB and OC respectively, then DEQP is

(a) a square
(b) a rectangle
(c) a rhombus
(d) a parallelogram

Answer :  (d) a parallelogram is correct

Hint:  To find Type of quadrilateral of DEQP.

D and E are mid-points of the sides AB and AC of ∆ABC and O is any point on the side BC. O is joined to A. If P and Q are mid-points of OB and OC respectively, then DEQP is

In ΔABC,D&E are the respective mid points of AB & AC.
∴DE ∥ (BC or PQ) ….(1)
Again in ΔABO,P&D are the respective mid points of AB & BO
∴DP ∥ AO … (2)
in ΔACO,EQ ∥ AO …(3)
∴ From (2) & (3), we get
DP ∥ EQ … (4)
∴ From (1) & (4), we have
DE ∥ PQ and DP ∥ EQ
Question 4. The quadrilateral formed by joining the mid-points of the sides of a quadrilateral PQRS, taken in order, is a rectangle if

(a) PQRS is a parallelogram
(b) PQRS is a rectangle
(c) the diagonals of PQRS are perpendicular to each other
(d) the diagonals of PQRS are equal.

Answer : (c) the diagonals of PQRS are perpendicular to each other is correct

Hint : A, B, C and D are the mid-points of the sides PQ, QR, RS and SP respectively

The quadrilateral formed by joining the mid-points of the sides of a quadrilateral PQRS, taken in order, is a rectanlge if (a) PQRS is a parallelogram (b) PQRS is a rectangle (c) the diagonals of PQRS are perpendicular to each other (d) the diagonals of PQRS are equal.

The quadrilateral formed by joining the mid-points A, B, C, D is ABCD

ABCD will be rectangle if the diagonal of PQRS bisect each other

Question 5. The quadrilateral formed by joining the mid-points of the sides of a quadrilateral ABCD, taken in order, is a rhombus if

(a) ABCD is a parallelogram
(b) ABCD is a rhombus
(c) the diagonals of ABCD are equal
(d) the diagonals of ABCD are perpendicular to each other.

Answer : (c) the diagonals of ABCD are equal is correct

Hint:   P, Q, R and S are the mid-points of the quadrilateral ABCD and a quadrilateral is formed by joining the mid-points in order

The quadrilateral formed by joining the mid-points of the sides of a quadrilateral ABCD, taken in order, is a rhombus if

PQRS will be a rhombus if the diagonals of ABCD are equal

Question 6. The figure formed by joining the mid points of the sides of a quadrilateral

ABCD, taken in order, is a square only if
(a) ABCD is a rhombus r
(b) diagonals of ABCD are equal
(c) diagonals of ABCD are perpendicular to each other
(d) diagonals of ABCD are equal and perpendicular to each other.

Answer : (d) diagonals of ABCD are equal and perpendicular to each other. is correct

Hint:

The figure formed by joining the mid points of the sides of a quadrilateral ABCD, taken in order, is a square only if (a) ABCD is a rhombus r (b) diagonals of ABCD are equal (c) diagonals of ABCD are perpendicular to each other (d) diagonals of ABCD are equal and perpendicular to each other.

PQRS are the mid point of the quadrilateral ABCD and a quadrilateral is formed by joining them in order.
