Primary 4 Mathematics - Geometry Quiz 01 - Answer Key


Section A: Multiple Choice Questions (1 mark each)

1. B) 90°
A right angle is exactly 90°.

2. C) Obtuse angle
An obtuse angle is between 90° and 180°.

3. D) 4
A square has 4 lines of symmetry (2 diagonal and 2 through midpoints of opposite sides).

4. B) 180°
The sum of interior angles in any triangle is 180°.

5. C) Trapezium
A trapezium has exactly one pair of parallel sides.


Section B: Short Answer Questions (2 marks each)

6. An acute angle is an angle that is less than 90°.
Award 2 marks for correct definition.

7. Rhombus
A rhombus has all four sides equal but only opposite angles are equal.

8. 9 cm
Perimeter = 4 × side, so side = 36 ÷ 4 = 9 cm

9. 40 cm
Perimeter = 2 × (length + breadth) = 2 × (12 + 8) = 2 × 20 = 40 cm

10. 60°
Third angle = 180° - 45° - 75° = 60°


Section C: Problem Solving (2 marks each)

11. 16 m
Perimeter = 4 × side
64 = 4 × side
Side = 64 ÷ 4 = 16 m

12. 10 cm
Perimeter = 2 × (length + breadth)
50 = 2 × (15 + breadth)
25 = 15 + breadth
Breadth = 25 - 15 = 10 cm

13. Right angle (90°)
3 × 30° = 90°, which is a right angle

14. 60°; Equilateral triangle
Third angle = 180° - 60° - 60° = 60°
Since all angles are 60°, it is an equilateral triangle.

15. 400 m
Perimeter = 2 × (120 + 80) = 2 × 200 = 400 m


Marking Scheme Summary

  • Section A: 5 marks (5 questions × 1 mark)
  • Section B: 10 marks (5 questions × 2 marks)
  • Section C: 10 marks (5 questions × 2 marks)
  • Total: 25 marks
