Geometry is the branch of mathematics that deals with shapes, sizes, and properties of spaces. Here are some fundamental concepts:

1. Basic Elements

  • Point (📍): A location in space with no size or dimension.
  • Line (📏): A straight path extending infinitely in both directions.
  • Plane (🗺️): A flat, two-dimensional surface that extends infinitely.
  • Solid (📦): A three-dimensional object with length, width, and height.

2. Key Principles

  • Euclidean Geometry: Based on the axioms of Euclid, focusing on flat spaces.

  • Non-Euclidean Geometry: Studies curved spaces (e.g., spherical or hyperbolic).

  • Congruence: Shapes that have the same size and shape.

3. Applications

  • Used in architecture, engineering, and computer graphics.
  • Helps in understanding spatial relationships and measurements.
