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.
(i) AC and BD are the two diagonals
(ii) (AB and CD) and (AD and BC) are the two pairs of opposite sides.
(iii) (∠A and ∠C) and (∠B and ∠D) are the two pairs of opposite angles.
(iv) (AB and BC) and (AD and DC) are the two pairs of adjacent sides.
(v) (∠A and ∠B) and (∠C and ∠D) are the two pairs of opposite angles.
2. Draw a parallelogram ABCD in which AB = 6.5 cm, AD = 4.8 cm and ∠BAD = 700.
Measure its diagonals.
Since, ABCD is a parallelogram
∴ AB = CD = 6.5 cm and
AD = BC = 4.8 cm
Given ∠BAD = 700
Steps of construction
1. Draw AD such that AD = 4.8 cm
2. Make an angle measuring 700 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.
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 × 4 = 12 cm
4x = 4 × 4 = 16 cm
∴ 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.
(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
Mark () against the correct answer in each of the following:
1. The sum of all the angles of a quadrilateral is
The sum of all the angles of a quadrilateral is 3600
Option (c) is the correct answer
2. The three angles of a quadrilateral are 800, 700 and 1200. The fourth angle is
Given the three angles of a quadrilateral are 800, 700 and 1200
Let the fourth angle be x
We know that sum of all the angles of a quadrilateral is 3600
800 + 700 + 1200 + x = 3600
2700 + x = 3600
x = 3600 – 2700
x = 900
∴ Fourth angle is 900
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
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 3600
∴ 3x + 4x + 5x + 6x = 3600
18x = 3600
x = 3600 / 18
x = 200
3x = 3 × 200 = 600
4x = 4 × 200 = 800
5x = 5 × 200 = 1000
6x = 6 × 200 = 1200
Hence, the largest angle is 1200
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
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
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.
