Question 1 · 1 mark · Difficulty 1/3

The exterior angle of a regular polygon is 24°. How many sides does the polygon have?

  1. 12
  2. 15
  3. 18
  4. 20
Show answer & explanation
✓ Answer: B15
Award 1 mark for correct answer. The sum of exterior angles of any polygon is 360°. For a regular polygon, each exterior angle = 360° ÷ n. Therefore n = 360° ÷ 24° = 15. A is incorrect — this would give exterior angles of 30°. C is incorrect — this would give exterior angles of 20°. D is incorrect — this would give exterior angles of 18°.
Question 2 · 1 mark · Difficulty 1/3

What is the sum of the interior angles of a hexagon?

  1. 540°
  2. 720°
  3. 900°
  4. 1080°
Show answer & explanation
✓ Answer: B720°
Award 1 mark for correct answer. Using the formula (n-2) × 180° where n = 6: (6-2) × 180° = 4 × 180° = 720°. A is incorrect — this is the sum for a pentagon (n=5). C is incorrect — this is the sum for a heptagon (n=7). D is incorrect — this is the sum for an octagon (n=8).

CIE IGCSE Mathematics: Geometry: Angles and properties of polygons (interior and exterior angles) FAQ

How many CIE IGCSE Mathematics questions on Geometry: Angles and properties of polygons (interior and exterior angles) are there on Kramizo?
Kramizo currently has 40 exam-board-aligned practice questions on Geometry: Angles and properties of polygons (interior and exterior angles) for CIE IGCSE Mathematics, with new questions added every week. Each question gives you instant feedback and a full examiner-style mark scheme that tells you exactly what would earn marks on a real CIE paper. The questions span the full difficulty range — from straightforward recall (level 1) right up to multi-step reasoning and evaluation (level 3) — so the bank works for first-pass revision and final exam-week stress testing alike.
Is Kramizo free for CIE IGCSE students preparing for Mathematics?
Yes — completely free. Every student gets 45 questions a day on the free plan, with no card required and no trial countdown. That free quota works across every subject and every topic in our bank, so you can mix Geometry: Angles and properties of polygons (interior and exterior angles) practice with other Mathematics topics or even switch to a totally different CIE subject without paying anything. Kramizo's optional Pro plan removes the daily cap and adds detailed progress analytics, but the free tier is the real product — used by thousands of GCSE, IGCSE and CSEC students.
Are the Geometry: Angles and properties of polygons (interior and exterior angles) 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 Geometry: Angles and properties of polygons (interior and exterior angles) typically tested on CIE IGCSE Mathematics papers?
Geometry: Angles and properties of polygons (interior and exterior angles) 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.
