Try a sample Identify angles by name question
Question 1 — Easy
A clock shows 10:45 am. What angle does the minute hand make with the 12 o'clock position, measured clockwise?
Answer: The minute hand moves 360° in 60 minutes, so each minute = 6°. At 45 minutes past, the angle = 45 × 6 = 270° clockwise from 12.
Question 2 — Medium
A straight road crosses another straight road, forming four angles. One of the angles measures 130°. Which of the following correctly names all four angles formed at the intersection?
Answer: When two straight lines intersect, they form two pairs of equal opposite angles, and the angles on a straight line must add to 180°. Since 180° − 130° = 50°, there are two obtuse angles of 130° and two acute angles of 50°. Option B is wrong because the remaining angles are 50°, not 90°; Option C is wrong because all four angles cannot be 130° (they must sum to 360°, and 4 × 130° = 520°); Option D is wrong because 130° is obtuse, not reflex — reflex angles are greater than 180°.
Question 3 — Hard
A student draws a shape with four angles. Three of the angles measure 75°, 110°, and 90°. What type of angle is the fourth angle of the shape?
Answer: The angles in any quadrilateral sum to 360°. Adding the three known angles: 75° + 110° + 90° = 275°, so the fourth angle is 360° − 275° = 85°. Wait — that gives 85°, which is acute. Let me recheck: 75 + 110 + 90 = 275, and 360 − 275 = 85°, which is acute (less than 90°). The correct answer should be D: Acute. The fourth angle is 85°, which is less than 90°, making it an acute angle. Students who choose A (Reflex) may think angles in a quadrilateral sum to more than 360°; students who choose B (Obtuse) may misidentify 85° as greater than 90°; students who choose C (Right) may assume the missing angle must equal one of the others.
