Geometry – what is it?

Geometry is a branch of mathematics that deals with the study of shapes, sizes, relative positions of figures, and the properties of space. It includes the study of points, lines, angles, surfaces, and solids. Geometry is a fundamental branch of mathematics and has numerous practical applications in fields such as engineering, physics, and architecture. Some of the main topics studied in geometry include:

  1. Points: A point is a location in space that has no size or dimensions. It is represented by a dot and is used to define the position of other geometric objects.
  2. Lines: A line is a straight path that extends indefinitely in both directions. It is represented by a straight line with arrows at both ends to show that it goes on forever.
  3. Angles: An angle is formed when two lines meet at a point. It is measured in degrees and can be acute, right, or obtuse.
  4. Surfaces: A surface is a two-dimensional shape that extends in all directions. Examples of surfaces include planes and circles.
  5. Solids: A solid is a three-dimensional object that takes up space. Examples of solids include cubes, spheres, and cylinders.
