An angle which is greater than 180° but less than 360° is called :
A
An actue angle
B
An obtuse angle
C
An adjacent angle
D
A reflex angle
» Explain it
Correct Option:
D
An angle which is greater than 180° but less than 360° is called a reflex angle.
Hence, option D is correct.

The complement of 72° 40’ is :
A
107° 20’
B
27° 20’
C
17° 20’
D
12° 40’
» Explain it
Correct Option:
C
Complement of 72° 40’ is 90° ‒ (72° 40’)
= (89° 60’) ‒ (72° 40’) {since 1° = 60’}
= 17° 20’
Hence, option C is correct.

The supplement of 154° 30’ is :
A
25° 30’
B
44° 45’
C
158° 45’
D
168° 30’
» Explain it
Correct Option:
A
Supplement of 154° 30’ is 180° ‒ (154° 30’)
= (179° 30’) ‒ (154° 30’) {since 1° = 60’}
= 25° 30’.
Hence, option A is correct.

Two straight lines AB and CD cut each other at O. If ∠BOD = 63°, then ∠BOC is :
A
63°
B
117°
C
17°
D
153°
» Explain it
Correct Option:
B
As given ∠BOD = 63°
Since COD is a straight line, we have :
∠BOC + ∠BOD = 180°. So, ∠BOC = (180° ‒ 63°) = 117°.
Hence, option B is correct.

The straight lines AD and BC intersect one another at the point O.
If ∠AOB + ∠BOD + ∠DOC = 274°, then ∠AOC is :
A
86°
B
90°
C
94°
D
137°
» Explain it
Correct Option:
A
As we know that the sum of all the angles around a point is 360°.
(∠AOB + ∠BOD + ∠DOC) + ∠AOC = 360°
∴ 274° + ∠AOC = 360° or ∠AOC = 86°.
Hence, option A is correct.
