Solved Questions on Geometric Shapes and Solids

1. Which of the following angles is the full rotation angle?

a)
b)
c)
d)

Answer: d)

Explanation: A full rotation angle is an angle exactly equal to 360°. It is also known as a full or complete angle. When you travel all the way around in a circle, you have completed a full rotation.

2. Which of the following angles is NOT the measure of an obtuse angle?

a)
b)
c)
d)

Answer: d)

Explanation: An obtuse angle is an angle larger than a right angle such as

An acute angle is an angle smaller than a right angle such as:

3. Which angle is formed by four times of the given angle?

a) Acute angle
b) Right angle
c) Straight angle
d) Reflex angle

Answer: c) Straight angle

Explanation: The given angle = 45° 
The angle formed by four times of the given angle = 4 45°
                                                                         = 180°
180° is a straight angle.

4. Which type of angle is made by the hands of the given clock?

a) Acute angle
b) Obtuse angle
c) Reflex angl
d) Straight angle 

Answer: b) Obtuse angle

Explanation: The angle made by the hand of the clock is more than 90° and less than 180°. Thus, the angle is an obtuse angle.

5. Which of the following shapes has the maximum number of sides?

a)
b)
c)
d)

Answer: a)

Explanation: In shape (a), the number of sides is 12.
In shape (b), the number of sides (straight line) is 2.
In shape (c), the number of sides is 7.
In shape (d), the number of sides is 10.

The maximum number of sides is in shape in option (a) i.e. 12.
