Geometry and trigonometry are two branches of mathematics that are often studied together. Geometry is the study of shapes, sizes, and relative positions of figures in space, while trigonometry is the study of relationships between angles and sides of triangles. Both fields are essential for understanding the physical world, as they are used to calculate distances, angles, and other measurements. The term MATH is an acronym for these two fields, with the letter M standing for geometry and the letter A standing for trigonometry.
