Question 1 · 1 mark · Difficulty 1/3

A cube has side length 8 cm. What is the length of the diagonal AG that runs from one corner of the cube to the opposite corner through the interior?

  1. 8√2 cm
  2. 8√3 cm
  3. 16 cm
  4. 24 cm
Show answer & explanation
✓ Answer: B8√3 cm
Award 1 mark for recognising the space diagonal formula d = a√3 where a is the side length. The space diagonal = 8√3 ≈ 13.9 cm. A is incorrect — this gives the face diagonal (8√2). C is incorrect — this is simply 2 × 8. D is incorrect — this is 3 × 8, adding the sides incorrectly.
Question 2 · 1 mark · Difficulty 1/3

A vertical flagpole stands at one corner of a horizontal rectangular field ABCD. The flagpole is 12 m tall. From point B, which is 16 m from the base of the flagpole, the angle of elevation to the top of the flagpole is θ. What is the value of tan θ?

  1. 0.75
  2. 1.33
  3. 0.80
  4. 0.60
Show answer & explanation
✓ Answer: A0.75
75. Award 1 mark for tan θ = opposite/adjacent = 12/16 = 0.75. B is incorrect — this gives 16/12 which is the reciprocal (cot θ). C is incorrect — this confuses the calculation with sin θ. D is incorrect — this would require a different height or distance.

Are the Trigonometry: Trigonometry in three dimensions questions aligned to the official CIE IGCSE Mathematics syllabus?
Every question is written against the published CIE IGCSE Mathematics specification, including the exact command words (state, describe, explain, calculate, evaluate, etc.), mark allocations, and difficulty tier you'd see on a real CIE paper. Explanations are written in the style of official examiner mark schemes — they tell you what is being awarded marks and why distractors are wrong, not just whether you got it right. The bank is continually refined to match the latest syllabus updates from CIE.
How is Trigonometry: Trigonometry in three dimensions typically tested on CIE IGCSE Mathematics papers?
Trigonometry: Trigonometry in three dimensions appears across multiple question types on real CIE IGCSE Mathematics papers — most commonly as multiple-choice questions in the objective section, structured short-answer questions in the main paper, and occasionally as part of an extended response. Kramizo's practice bank reflects that mix: 4-option MCQs, true/false statements, fill-in-the-blank key terms, multi-select questions, and ordering questions. Working through the bank gives you exposure to every question style examiners actually use.
