二次公式：x = [-b ± √b² - 4ac] / 2a
6. Geometry and Shape | 几何与图形
Geometry topics include properties of angles (alternate, corresponding, supplementary), triangles, quadrilaterals, polygons, and circles. Students apply Pythagoras' theorem and trigonometric ratios (sine, cosine, tangent) to solve problems involving right-angled triangles. They also explore similarity, scale factors, and transformations such as reflection, rotation, translation, and enlargement.
几何主题包括角（内错角、同位角、补角）、三角形、四边形、多边形和圆的性质。学生运用毕达哥拉斯定理和三角比（正弦、余弦、正切）解决涉及直角三角形的问题。他们还探索相似性、比例因子以及反射、旋转、平移和放大等变换。
