In a circle, the angle subtended by an arc at the centre is 124°. What is the angle subtended by the same arc at any point on the major arc?

Q: How do I try a free CIE Mathematics question?

Just tap any of the four options on this page — no signup, no card, nothing to install. You'll see the correct answer and a full mark-scheme-style explanation within a second. Each visit shows a fresh randomly-picked question from the live CIE IGCSE Mathematics bank, so you can keep refreshing to try different ones before deciding whether to create a free account for daily access.

Q: Is Kramizo really free for CIE Mathematics students?

Yes — completely free. Every student gets 45 questions a day on the free plan, across any board and any subject, with no card required and no trial countdown. Kramizo's optional Pro plan removes the daily cap and adds analytics, but the free plan is genuinely free forever. We make money from the small percentage of students who choose to upgrade — not from selling data or ads.

Q: Are the Mathematics questions aligned to the CIE IGCSE syllabus?

Every question is written against the published CIE IGCSE Mathematics syllabus and reviewed for accuracy before being added to the bank. We match the command words (state, describe, explain, evaluate), mark allocations, and difficulty tier you'll see on real CIE past papers. Explanations are written in the style of official examiner mark schemes so students learn exactly what marks are being awarded for.

Question

In a circle, the angle subtended by an arc at the centre is 124°. What is the angle subtended by the same arc at any point on the major arc?

Accepted Answer

62° — The inscribed angle theorem states that the angle at the centre is twice the angle at the circumference when subtended by the same arc. So the angle at the circumference = 124° ÷ 2 = 62°. Option B (236°) is the reflex angle at the centre. Option C repeats the centre angle, ignoring the theorem. Option D halves the answer again unnecessarily.
