Video Definition 3--3D Geometry--Base (Geometry) | Base (Geometry)
Topic3D Geometry DefinitionThe base of a geometric figure is the surface a solid object stands on or the bottom line of a shape like a triangle or rectangle. DescriptionThe concept of a base is fundamental in geometry as it provides a reference point for measuring height and calculating area and volume. In real-world applications, the base is crucial in construction and design, where the stability of a structure often depends on its base. In mathematics, the base is used to derive formulas for area and volume, such as the volume V of a prism: V = Base Area × Height |
