1.

Check for the validity of the statement.

'Measure of an obtuse angle is more than90°.'

'Measure of an obtuse angle is more than

a. | never true | ||

b. | always true | ||

c. | sometimes true | ||

d. | not enough information |

The statement is always true.

Correct answer : (2)

2.

What type of angle is represented in the figure?

a. | a right angle | ||

b. | a straight angle | ||

c. | an obtuse angle | ||

d. | an acute angle |

So, the angle represented by the figure is a right angle.

Correct answer : (1)

3.

What type of angle do the hands of a clock form when it is 2 O′Clock?

a. | obtuse angle | ||

b. | straight angle | ||

c. | acute angle | ||

d. | right angle |

The angles formed by the

Correct answer : (3)

4.

What is the angle formed by the hands of the clock as shown in the picture?

a. | an acute angle | ||

b. | an obtuse angle | ||

c. | a right angle | ||

d. | a straight angle |

The angle shown by the hands of the clock also measures 90° and are perpendicular to each other.

So, the angle formed by the hands of a clock is a right angle.

Correct answer : (3)

5.

Identify the correct statement(s).

1. An acute angle is an angle less than 90°.

2. A right angle is an angle whose measure is equal to 90°.

3. The sum of two acute angles will be always greater than a right angle.

4. An obtuse angle is an angle whose measure is less than 90°.

1. An acute angle is an angle less than 90°.

2. A right angle is an angle whose measure is equal to 90°.

3. The sum of two acute angles will be always greater than a right angle.

4. An obtuse angle is an angle whose measure is less than 90°.

a. | only 1 & 2 | ||

b. | only 1 | ||

c. | only 2 | ||

d. | only 3 & 4 |

A right angle is an angle whose measure is equal to 90°.

An obtuse angle is an angle greater than 90° and whose measure is between 90° and 180°.

Let us assume

So, statements 1 & 2 only are correct.

Correct answer : (1)

6.

Identify the figure with a right angle.

a. | Figure 4 | ||

b. | Figure 2 | ||

c. | Figure 1 | ||

d. | Figure 3 |

So, among the figures, Figure 4 represents a right angle.

Correct answer : (1)

7.

Identify the figure with an angle greater than a right angle.

a. | Figure 2 | ||

b. | Figure 1 | ||

c. | Figure 3 | ||

d. | Figure 4 |

Among the figures, the angle of Figure 4 is greater than a right angle.

Correct answer : (4)

8.

How many right angles does the given polygon have?

a. | 4 | ||

b. | 3 | ||

c. | 2 | ||

d. | 6 |

So, the given polygon has 4 right angles.

[Since, a square has 4 right angles.]

Correct answer : (1)

9.

Identify the number of right angles in the given polygon.

a. | 8 | ||

b. | 4 | ||

c. | 2 |

The number of right angles in the given polygon is 0.

Correct answer : (2)

10.

What is the angle formed by the hands of the clock?

a. | an acute angle | ||

b. | an obtuse angle | ||

c. | a straight angle | ||

d. | a right angle |

Any angle greater than 90° but smaller than 180° is called an obtuse angle.

So, the angle formed by the hands of a clock is an obtuse angle.

Correct answer : (2)
