Part B: Objective Questions (1 Mark Each)
Choose the correct answer and write the option (a/b/c/d)
(1) A right angle measures:
(a) 30° (b) 45° (c) 90° (d) 180°
Correct! A right angle always measures 90°.
(2) The instrument used to measure angles is:
(a) Compass (b) Protractor (c) Divider (d) Ruler
Correct! A protractor is specifically designed to measure angles.
(3) An acute angle is:
(a) Less than 90° (b) Equal to 90° (c) Greater than 90° (d) Equal to 180°
Correct! Acute angles are always less than 90°.
(4) A straight angle measures:
(a) 90° (b) 120° (c) 150° (d) 180°
Correct! A straight angle forms a straight line and measures 180°.
(5) Which of these angles is obtuse?
(a) 45° (b) 90° (c) 120° (d) 180°
Correct! 120° is between 90° and 180°, so it's obtuse.
(6) One complete revolution equals:
(a) 90° (b) 180° (c) 270° (d) 360°
Correct! A complete revolution is 360°.
(7) The supplement of a 110° angle is:
(a) 60° (b) 70° (c) 80° (d) 90°
Correct! Supplement = 180° - 110° = 70°.
(8) The complement of a 45° angle is:
(a) 35° (b) 40° (c) 45° (d) 55°
Correct! Complement = 90° - 45° = 45°.
(9) Which of these angles is reflex?
(a) 60° (b) 120° (c) 180° (d) 270°
Correct! Reflex angles are between 180° and 360°. 270° qualifies.
(10) The sum of the measures of supplementary angles is always:
(a) 90° (b) 120° (c) 150° (d) 180°
Correct! Supplementary angles always add up to 180°.
