Cambridge IGCSE Mathematics practice

exam practice - 1. Determine unknown angles and provide basic explanations using these geometric properties: the total of angles around a point is 360°, the total of angles on a straight line is 180°, vertically opposite angles are equal, the angle sum in a triangle is 180°, and in a quadrilateral is 360°. 2. Find unknown angles and explain geometrically the angles created by parallel lines: corresponding angles are equal, alternate angles are equal, and co-interior angles add up to 180° (supplementary). 3. Understand and apply the angle properties of regular polygons, including both exterior and interior angles, as well as the angle sum. - Angles
