  1. A helicopter flies 10 km South, then 10 km East. What single direction must it fly to return directly to its base?

    Answer: North-West

    The helicopter is now south and east of base, so it must travel in the opposite direction: North-West.

  2. How many faces does a triangular prism have?

    Answer: 5

    A triangular prism has 2 triangular end faces and 3 rectangular side faces, totalling 5 faces.

  3. A rectangular room is 6 m long and 4 m wide. What is the straight-line distance from one corner to the diagonally opposite corner?

    Answer: 7.2 m

    Using Pythagoras: √(6² + 4²) = √52 ≈ 7.2 m.

  4. A shape has 4-fold rotational symmetry. What is the smallest angle it can be rotated to look identical to its original position?

    Answer: 90°

    4-fold symmetry means the shape repeats every 360° ÷ 4 = 90° of rotation.

  5. On a standard die, opposite faces always sum to 7. If 3 is on top, what number is on the bottom?

    Answer: 4

    Since opposite faces sum to 7 and 3 is on top, the bottom face must show 7 − 3 = 4.

  6. A soldier faces South-East. They turn 135° anti-clockwise. What direction are they now facing?

    Answer: North

    South-East is at bearing 135°; subtracting 135° for anti-clockwise rotation gives bearing 0°, which is North.

  7. A 2D shape is reflected over a vertical line. Which property is changed?

    Answer: Orientation (handedness)

    Reflection preserves size, area, and perimeter but reverses the handedness (chirality) of the shape.
