The 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.

Description

The 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
