**Exercise 17A PAGE NO: 202**

**1. In the adjacent figure, a quadrilateral has been shown.**

**Name: (i) its diagonals,**

** (ii) two pairs of opposite sides,**

** (iii) two pairs of opposite angles,**

** (iv) two pairs of adjacent sides,**

** (v) two pairs of adjacent angles.**

**Solution**

(i) AC and BD are the two diagonals

(ii**) (**AB and CD) and (AD and BC) are the two pairs of opposite sides.

(iii) (âˆ A and âˆ C) and (âˆ B and âˆ D) are the two pairs of opposite angles.

(iv) (AB and BC) and (AD and DC) are the two pairs of adjacent sides.

(v) (âˆ A and âˆ B) and (âˆ C and âˆ D) are the two pairs of adjacent angles.

**2. Draw a parallelogram ABCD in which AB = 6.5 cm, AD = 4.8 cm and âˆ BAD = 70 ^{0}.**

**Measure its diagonals.**

**Solution**

Since, ABCD is a parallelogram

âˆ´ AB = CD = 6.5 cm and

AD = BC = 4.8 cm

Given âˆ BAD = 70^{0}

Steps of construction

1. Draw AD such that AD = 4.8 cm

2. Make an angle measuring 70^{0} at A and cut an arc of 6.5 cm and name it as B

3. From B cut an arc of 4.8 cm and 6.5 cm from D, name it as C

4. Join AB, BC and CD

5. By measuring the diagonals AC and BD we get AC = 9.2 cm and BD = 6.6 cm

**3. Two sides of a parallelogram are in the ratio 4 : 3. If its perimeter is 56 cm, find the lengths of its sides.**

**Solution**

Given two sides of parallelogram are in the ratio 4: 3

In a parallelogram we know that opposite sides are equal and parallel. Hence, they are also in ratio 4: 3 which is 4x and 3x

Perimeter = 4x + 3x + 4x + 3x = 56

14x = 56

x = 56 / 14

x = 4

3x = 3 Ã— 4 = 12 cm

4x = 4 Ã— 4 = 16 cm

âˆ´ the length of its sides are 12 cm, 16 cm, 12 cm and 16 cm

**4. Name each of the following parallelograms:**

**(i) The diagonals are equal and the adjacent sides are unequal.**

**(ii) The diagonals are equal and the adjacent sides are equal.**

**(iii) The diagonals are unequal and the adjacent sides are equal.**

**Solution**

(i) In a rectangle the diagonals are equal and the sides are unequal

(ii) In a square the diagonals are equal and the adjacent sides are equal

(iii) In a rhombus the diagonals are unequal and the adjacent sides are equal

**Exercise 17B PAGE nO: 203**

**OBJECTIVE QUESTIONS**

**Mark () against the correct answer in each of the following:**

**1. The sum of all the angles of a quadrilateral is**

**(a) 180 ^{0}**

**(b) 270 ^{0}**

**(c) 360 ^{0}**

**(d) 400 ^{0}**

**Solution**

The sum of all the angles of a quadrilateral is 360^{0}

Option (c) is the correct answer

**2. The three angles of a quadrilateral are 80 ^{0}, 70^{0} and 120^{0}. The fourth angle is**

**(a) 110 ^{0}**

**(b) 100 ^{0}**

**(c) 90 ^{0}**

**(d) 80 ^{0}**

**Solution**

Given the three angles of a quadrilateral are 80^{0}, 70^{0} and 120^{0}

Let the fourth angle be x

We know that sum of all the angles of a quadrilateral is 360^{0}

80^{0} + 70^{0} + 120^{0} + x = 360^{0}

270^{0} + x = 360^{0}

x = 360^{0} – 270^{0}

x = 90^{0}

âˆ´ Fourth angle is 90^{0}

Option (c) is the correct answer.

**3. The angles of a quadrilateral are in the ratio 3 : 4 : 5 : 6. The largest of these angles is**

**(a) 90 ^{0}**

**(b) 120 ^{0}**

**(c) 150 ^{0}**

**(d) 102 ^{0}**

**Solution**

Given the angles of quadrilateral are in the ratio 3: 4: 5: 6

Let the angles of quadrilateral be 3x, 4x, 5x and 6x

We know that sum of all angles of quadrilateral is 360^{0}

âˆ´ 3x + 4x + 5x + 6x = 360^{0}

18x = 360^{0}

x = 360^{0} / 18

x = 20^{0}

3x = 3 Ã— 20^{0} = 60^{0}

4x = 4 Ã— 20^{0} = 80^{0}

5x = 5 Ã— 20^{0} = 100^{0}

6x = 6 Ã— 20^{0} = 120^{0}

Hence, the largest angle is 120^{0}

Option (b) is the correct answer

**4. A quadrilateral having one and only one pair of parallel sides is called**

**(a) a parallelogram**

**(b) a kite**

**(c) a rhombus**

**(d) a trapezium**

**Solution**

A quadrilateral having one and only one pair of parallel sides is called trapezium

Option (d) is the correct answer.

**5. A quadrilateral whose opposite sides are parallel is called**

**(a) a rhombus**

**(b) a kite**

**(c) a trapezium**

**(d) a parallelogram**

**Solution**

A quadrilateral in which both pairs of opposite sides are parallel is called parallelogram

Option (d) is the correct answer.

### Chapter Brief of RS Aggarwal Solutions for Class 6 Maths Chapter 17 – Quadrilaterals

A closed figure or a polygon with four sides and four angles is known as a Quadrilateral. Parallelogram, rectangle, square, trapezoid and rhombus are the different types of Quadrilaterals. Mobiles, laptops, computers, books, copies, chart papers etc. are examples of Quadrilaterals.
