In geometry, a point is a fundamental concept that represents a precise location in space. It has no length, width, depth, or any other dimensional attribute—essentially, it is a zero-dimensional object. Points are usually denoted by a capital letter (e.g., A, B, C) and can be represented on a coordinate system by ordered pairs or triplets (for two-dimensional or three-dimensional spaces, respectively). Points serve as the building blocks for more complex geometric shapes and constructions.
