Geometric shapes and figures


Geometry is a branch of mathematics that focuses on the study of shapes, sizes, dimensions, and properties of figures and spaces. It is concerned with properties of space that are related to distance, shape, size, and relative position of figures.

The Basics of Geometry

Geometry is fundamentally divided into two categories: plane geometry, which deals with objects like points, lines, and circles that are entirely contained in a single plane, and solid geometry, which deals with objects in three-dimensional space.

Plane vs Solid Geometry

Plane and solid geometry

Key Concepts in Geometry

  • Points and Lines: The most basic elements in geometry.
  • Angles: Measures the inclination between two lines.
  • Polygons: Multi-sided figures, like triangles and quadrilaterals.
  • Circles: All points equidistant from a given point.

Types of Geometry

Euclidean Geometry

Based on the postulates of the Greek mathematician Euclid.

Non-Euclidean Geometry

Includes hyperbolic and elliptic geometry, where Euclid's parallel postulate doesn't hold.

Analytic Geometry

Uses coordinates to define geometric shapes.

Applications of Geometry

  1. Architecture: For designing buildings and structures.
  2. Art: In creating proportional and symmetrical designs.
  3. Astronomy: For calculating distances and sizes of celestial bodies.
  4. Engineering: In designing mechanical structures and electrical circuits.
