Question 1
1 / -0

Which of the following statements is true?

A
A line has a finite length.

B
A line segment has infinite length.

C
Two lines cannot pass through the same point.

D
There can be at most one common point between two non-parallel lines.

Solution

There can be at most one common point between two non-parallel lines.
Question 2
1 / -0

Which of the following is an acute angle?

A
62^o

B
90^o

C
95^o

D
185^o

Solution

An acute angle is always less than 90^o.
As 62^o < 90^o

Therefore, 62^o is an acute angle.
Question 3
1 / -0

Which of the following pairs of angles is complementary?

A
140^o, 40^o

B
20^o, 80^o

C
10^o, 80^o

D
75^o, 25^o

Solution

Two angles are called complementary angles if their sum is 90^o.
As 10^o + 80^o = 90^o, so 10^o, 80^o is a pair of complementary angles.
Question 4
1 / -0

A line has _________ points.

A
two

B
five

C
seven

D
infinite

Solution

A line has infinite points.
Question 5
1 / -0

Which of the following pairs of angles is supplementary?

A
120^o, 60^o

B
110^o, 80^o

C
75^o, 15^o

D
125°, 65°

Solution

Two angles are called supplementary angles if their sum is 180^o.

As 120^o + 60^o = 180^o, so 120^o, 60^o is a pair of supplementary angles.
Question 6
1 / -0

Which of the following is an obtuse angle?

A
∠A = 135^o

B
∠B = 35^o

C
∠P = 90^o

D
∠R = 180^o

Solution

An angle measuring less than 90^o is known as an acute angle.
As 35^o < 90^o, so ∠B = 35^o is an acute angle.
Question 7
1 / -0

Which of the following pairs of angles is complementary?

A
70^o, 45^o

B
45^o, 45^o

C
140^o, 40^o

D
90^o, 10^o

Solution

Two angles are called complementary angles if their sum is 90⁰.
As 45⁰ + 45⁰ = 90⁰, so 45⁰, 45⁰ is a pair of complementary angles.
