Segment of a Circle

A segment of a circle is the region between a chord and the arc it cuts off, resembling a curved cap. Its area is found by taking the area of the sector and subtracting the triangle formed by the two radii and the chord: $\frac{1}{2}r^{2}(\theta-\sin\theta)$.

You meet Segment of a Circle in the Circular Measure chapter of SPM Additional Mathematics. Knowing the term precisely matters in the exam: questions often hinge on reading a keyword correctly, and because SPM marking is analytic, using the right definition in your working helps secure method marks.

Our teachers make sure a student can not only recite what Segment of a Circle means but use it fluently in a full solution.

Because the SPM Add Math paper is bilingual (BM/EN), it helps to know this term in each language: Segment of a Circle (EN) · Tembereng Bulatan (BM) · 弓形 (中文)
