(a) a ray
(b) a line
(c) an angle
(d) a line segment

Solution:

Option (c) is the correct answer.

The figure formed by two rays with the same initial point is known as an angle.

3. An angle of measure 0° is called
(a) a complete angle
(b) a right angle
(c) a straight angle
(d) None of these

Solution:

Option (d) is the correct answer.

An angle of measure 0° is called a zero angle.

4. An angle of measure 90° is called
(a) a complete angle
(b) a right angle
(c) a straight angle
(d) a reflex angle

Solution:

Option (b) is the correct answer.

An angle of measure 90° is called a right angle.

5. An angle of measure 180° is called
(a) a zero angle
(b) a right angle
(c) a straight angle
(d) a reflex angle

Solution:

Option (c) is the correct answer.

An angle of measure 180° is called a straight angle.

6. An angle of measure 360° is called
(a) a zero angle
(b) a straight angle
(c) a reflex angle
(d) a complete angle

Solution:

Option (d) is the correct answer.

An angle of measure 360° is called a complete angle.

7. An angle of measure 240° is
(a) an acute angle
(b) an obtuse angle
(c) a straight angle
(d) a complete angle

Solution:

An angle of measure 240° is called a reflex angle.

8. A reflex angle measures
(a) more than 90° but less than 180°
(b) more than 180° but less than 270°
(c) more than 180° but less than 360°
(d) None of these

Solution:

Option (c) is the correct answer.

A reflex angle measures more than 180° but less than 360°.

9. The number of degrees in 2 right angle is
(a) 90°
(b) 180°
(c) 270°
(d) 360°

Solution:

Option (b) is the correct answer.

The number of degrees in 2 right angle is 180°.

10. The number of degrees in 3/2 right angles is
(a) 180°
(b) 360°
(c) 270°
(d) 90°

Solution:

One right angle = 90°

So 3/2 right angles = 3/2 (90°) = 135o

11. If a bicycle wheel has 36 spokes, then the angle between a pair of adjacent spokes is
(a) 10°
(b) 15°
(c) 20°
(d) 12°

Solution:

Option (a) is the correct answer.

The central angle of a bicycle wheel measures 360°

The angle between a pair of adjacent spokes of the wheel which has 36 spokes = 360/ 36 = 10o
