Question 1
1 / -0

Which of the following pairs of angles is complementary?

A
60^o, 30^o

B
35^o, 30^o

C
70^o, 22^o

D
65^o, 35^o

Solution

Two angles are called complementary angles, if their sum is 90⁰.
Since 60⁰ + 30⁰ = 90⁰, so 60⁰, 30⁰ are complementary angles.
Question 2
1 / -0

An obtuse angle is always _____.

A
less than 90^o

B
equal to 90^o

C
greater than 180^o and less than 360^o

D
greater than 90^o and less than 180^o

Solution

An obtuse angle is always greater than 90⁰ and less than 180⁰.
Question 3
1 / -0

If three or more points lie on the same line, they are called _____.

A
congruent points

B
collinear points

C
non-collinear points

D
obtuse points

Solution

If three or more points lie on the same line, they are called collinear points.
Question 4
1 / -0

Which of the following is an obtuse angle?

A
35^o

B
90^o

C
110^o

D
185^o

Solution

An obtuse angle is always greater than 90⁰.
As 90⁰ < 110⁰ < 180⁰
So, 110⁰ is an obtuse angle.
Question 5
1 / -0

Which of the following pairs of angles is complementary?

A
74^o, 16^o

B
153^o, 27^o

C
71^o, 21^o

D
72^o, 38^o

Solution

Two angles are called complementary angles, f their sum is 90⁰.
As 74⁰ + 16⁰ = 90⁰, so 74⁰, 16⁰ is a pair of complementary angles.
Question 6
1 / -0

Which of the following statements is not true?

A
A line contains infinite points.

B
A line has infinite width.

C
A line has infinite length.

D
A line is a perfectly straight curve.

Solution

A line has infinite width is the false statement
