Section A: Multiple Choice Questions (10 marks)

1. How many degrees is a quarter turn? (2 marks)

Answer: (2) 90°

Explanation: A full turn is 360°. A quarter turn is ¼ × 360° = 90°

2. Which angle is a right angle? (2 marks)

Answer: (3) 90°

Explanation: A right angle is exactly 90°, like the corner of a square or rectangle.

3. Ahmad faces North. He makes a half turn clockwise. Which direction is he facing now? (2 marks)

Answer: (2) South

Explanation: A half turn (180°) from North leads to South, regardless of clockwise or anticlockwise direction.

4. Which type of angle is 135°? (2 marks)

Answer: (3) Obtuse angle

Explanation:

• Acute angle: less than 90°
• Right angle: exactly 90°
• Obtuse angle: between 90° and 180°
• Straight angle: exactly 180° 135° is between 90° and 180°, so it's obtuse.

5. How many lines of symmetry does a rectangle have? (2 marks)

Answer: (2) 2

Explanation: A rectangle has 2 lines of symmetry: one horizontal through the middle and one vertical through the middle.

6. Name each type of angle: (3 marks)

(a) 45° is a acute angle

(b) 90° is a right angle

(c) 150° is a obtuse angle

7. Complete these angle facts: (3 marks)

(a) A full turn = 360 degrees

(b) A half turn = 180 degrees

(c) A quarter turn = 90 degrees

8. Look at the rectangle ABCD. Name two pairs of: (3 marks)

(a) Parallel lines: AB and CD, BC and AD

(b) Perpendicular lines: AB and BC, BC and CD

(Any other correct combinations are acceptable)

9. Siti starts facing East. Complete the table: (3 marks)

Starting Direction	Turn	Final Direction
East	¼ turn clockwise	South
South	½ turn	North
West	¾ turn anticlockwise	South

Working:

• East + ¼ clockwise: East → South
• South + ½ turn: South → North
• West + ¾ anticlockwise: West → North → East → South

10. Find the missing angles: (3 marks)

(a) Angles on a straight line: 85° + ? = 180°
    **Missing angle = 95°**
    **Working:** 180° - 85° = 95°

(b) Angles around a point: 120° + 90° + ? = 360°
    **Missing angle = 150°**
    **Working:** 360° - 120° - 90° = 150°
    
(c) In a rectangle, all angles are **90°**

Section C: Word Problems (15 marks)

11. Mei Lin is playing a game. She starts facing North and follows these instructions: (4 marks)

• Turn ¼ turn clockwise
• Turn ½ turn anticlockwise
• Turn ¼ turn clockwise

What direction is she facing at the end?

Working:

• Start: North
• ¼ turn clockwise: North → East
• ½ turn anticlockwise: East → West
• ¼ turn clockwise: West → North

Answer: North

12. In rectangle PQRS, angle QPR = 35° and angle RPQ = 55°. (5 marks)

(a) What is angle PRQ?

Working: In triangle PQR: 35° + 55° + PRQ = 180° PRQ = 180° - 35° - 55° = 90°

Answer: 90°

(b) What type of triangle is PQR?

Answer: Right-angled triangle

(c) Explain why all the angles in rectangle PQRS are 90°.

Answer: A rectangle is defined as a quadrilateral with four right angles. This is a property of rectangles - all interior angles are exactly 90°.

13. Wei Ming drew a regular hexagon. He wants to find how many lines of symmetry it has. (3 marks)

(a) How many lines of symmetry does a regular hexagon have?

Answer: 6

(b) Draw ONE line of symmetry on this hexagon:

[Drawing should show a line through opposite vertices or through midpoints of opposite sides]

14. Look at this pattern of shapes: (3 marks)

○ △ □ ○ △ □ ○ △ □

(a) What comes next in the pattern?

Answer: ○ (circle)

(b) If this pattern continues, what will be the 15th shape?

Working: Pattern repeats every 3 shapes: ○ △ □ 15 ÷ 3 = 5 remainder 0 So the 15th shape is the same as the 3rd shape in the pattern.

Answer: □ (square)

(c) How many triangles will there be in the first 12 shapes?

Working: In every group of 3 shapes, there is 1 triangle. 12 ÷ 3 = 4 groups So there are 4 triangles.

Answer: 4

Common Mistakes to Watch For:

1. Confusing clockwise and anticlockwise rotations
2. Forgetting that angles on a straight line sum to 180°
3. Not understanding that angles around a point sum to 360°
4. Mixing up acute, right, and obtuse angles
5. Miscounting lines of symmetry in regular shapes
6. Getting lost when tracking multiple direction changes
