Introduction to Geometry

Geometry is a branch of mathematics concerned with the properties and relationships of points, lines, surfaces, and solids. It is fundamental in various fields such as engineering, architecture, physics, and computer science. Geometry can be divided into two major categories: plane geometry, which deals with two-dimensional shapes, and solid geometry, which deals with three-dimensional objects.

Plane Geometry

Plane geometry focuses on shapes and figures that lie in a two-dimensional plane. It encompasses the study of points, lines, angles, polygons, and circles.

Solid Geometry

Solid geometry is the study of three-dimensional shapes and figures. It includes the study of points, lines, planes, and various solids like cubes, spheres, cylinders, cones, and pyramids.
