How do we understand and apply geometry and trigonometry?

Understanding and Applying Geometry and Trigonometry

Geometry and trigonometry are fundamental branches of mathematics with wide-ranging applications in various scientific fields. Geometry deals with the properties and relations of points, lines, surfaces, and solids, while trigonometry focuses on the relationships between the angles and sides of triangles. Both subjects are essential for solving practical problems in physics, engineering, and other disciplines.
