What is Geometry?
Geometry is the branch of mathematics about shapes, sizes, positions, and space — points, lines, angles, surfaces, and solids. It's used everywhere from architecture and art to navigation and computer graphics.
See it, don’t just read it.

Key things to understand
- 1It studies shapes and their properties (length, area, angle, volume).
- 2Includes 2D shapes (triangles, circles) and 3D solids (cubes, spheres).
- 3Key ideas: angles, symmetry, congruence, and the Pythagorean theorem.
- 4It underpins design, engineering, maps, and graphics.
Frequently asked questions
- What is geometry used for?
- Architecture, engineering, art, navigation, computer graphics, and everyday measuring.
- What are the basic elements of geometry?
- Points, lines, angles, surfaces, and solids.
- What's the difference between 2D and 3D geometry?
- 2D deals with flat shapes (area); 3D deals with solid objects (volume).
