Meaning of Geometry

Geometry is the part of mathematics that studies different shapes and how they relate to each other.

Geometry is the branch of mathematics concerned with the properties and relations of points, lines, surfaces, solids, and higher dimensional analogues.

It is just the study of points, lines, and various shapes like squares or circles.

Geometry can be divided into two main parts:

Plane Geometry

This part of geometry talks about shapes that are flat like a piece of paper.

Plane Geometry deals with flat shapes such as lines, circles and triangles.

You can draw these on a flat surface, and they do not have any thickness.

Sometimes, you may even hear people call them two-dimensional or 2-D shapes. This means that you cannot touch them or hold them on all sides like you would hold a football or a brick.

Solid Geometry

This part of geometry talks about objects that take up space, like things you can hold in your hand.

Solid Geometry deals with three-dimensional (3-D) shapes such as cubes, prisms, cylinders and spheres.

These are shapes like a tin of milk or a box of matches.

Important Notes

3-dimensional figures are solid shapes having length, breadth and width.

2-dimensional figures are plane shapes having length and breadth but no width.

Key points

•Geometry is the branch of mathematics that studies the properties and relationships of points, lines, surfaces, and solids.
•Geometry is broadly divided into Plane Geometry and Solid Geometry.
•Plane Geometry focuses on two-dimensional (2-D) shapes like lines, circles, and triangles, which have length and breadth but no width.
•Solid Geometry deals with three-dimensional (3-D) shapes such as cubes, cylinders, and spheres, possessing length, breadth, and width.
