Primary 3 Mathematics Quiz - Geometry: Answer Key
Answer 1.
Angle A. It opens exactly 90 degrees, shown by the small square corner mark. (2 marks)
Answer 2.
(c) Triangle. A quadrilateral must have 4 sides; a triangle has only 3. (2 marks)
Answer 3.
6 faces. (2 marks)
Answer 4.
They are parallel lines. (2 marks)
Answer 5.
90°. (2 marks)
Answer 6.
Cylinder. (2 marks)
Answer 7.
9 edges. (2 marks)
Answer 8.
Perpendicular lines. (2 marks)
Answer 9.
A triangle. (2 marks)
Answer 10.
Angle R. It opens wider than a square corner, so it is greater than a right angle. (2 marks)
Answer 11.
6 sides. (2 marks)
Answer 12.
8 vertices. (2 marks)
Answer 13.
False. Only the opposite sides of a rectangle are equal in length. (2 marks)
Answer 14.
1 flat face (the circular base); the rest is a curved surface. (2 marks)
Answer 15.
One quarter (a quarter turn). (2 marks)
Answer 16.
A cube. Working: the net is made of 6 identical squares; folding gives 6 equal square faces, which form a cube. Method marks (4) + correct solid named (2). (6 marks)
Answer 17.
Trapezium, with 4 vertices. Working: 4 straight sides means it is a quadrilateral; exactly one pair of opposite sides parallel matches a trapezium; every quadrilateral has 4 vertices. Reasoning marks (4) + both answers (2). (6 marks)
Answer 18.
■ (square). Working: the pattern repeats every 3 shapes. 20 ÷ 3 = 6 remainder 2. Remainder 2 points to the 2nd shape in the group, which is ■. Method marks (4) + correct shape (2). (6 marks)
Answer 19.
(a) A right angle. The hands point to 12 and 3, a quarter turn of 90°. (b) Greater than a right angle. At 5 o'clock the hands point to 12 and 5; the gap is more than a quarter of the clock face, so the angle is larger than a right angle. (6 marks)
Answer 20.
8 cubes. Working: bottom layer 3 × 2 = 6 cubes; top layer 2 × 1 = 2 cubes; 6 + 2 = 8. Method marks (4) + correct total (2). (6 marks)
