iGCSE Syllabus Alignment
Cambridge iGCSE Maths (0580)
Apply sine, cosine and tangent ratios for any angle. Solve problems using the sine and cosine rules for any triangle. Use the formula area = ½ab sin C
TrigonometryEdexcel iGCSE Maths (4MA1)
Apply trigonometric ratios to find angles and lengths in right-angled triangles in 3D. Use the sine rule, cosine rule and area = ½ab sin C. Solve trigonometric problems in 2D and 3D
GeometryUse conventional terms and notation. Measure and draw angles to the nearest degree. Understand compass directions and three-figure bearings. Identify acute, obtuse, reflex and right angles
GeometryUnderstand and use circle theorems: angle in a semicircle is 90°; angle at centre is twice angle at circumference; angles in the same segment are equal; opposite angles of a cyclic quadrilateral sum to 180°; alternate segment theorem; tangent to a circle is perpendicular to the radius
