OBJECTIVE QUESTIONS

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

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

(a) 1800

(b) 2700

(c) 3600

(d) 4000

Solution

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

(a) 1100

(b) 1000

(c) 900

(d) 800

Solution

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

(a) 900

(b) 1200

(c) 1500

(d) 1020

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 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

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.
