# Geometric Shapes: List, Definition, Types of Geometric Shapes

Table of Contents

Mathematical geometric shapes are mathematical figures that represent the shapes of everyday objects. The geometry of shapes is the study of objects with boundaries, angles, and surfaces. Two-dimensional and three-dimensional shapes are both studied.

Similarly, shapes are classified according to their regularity or uniformity. A regular shape is usually symmetrical, such as a square or circle. Asymmetrical shapes are irregular shapes. They are also called organic shapes or freeform shapes. Trees, for example, have irregular shapes.

Two-dimensional shapes in plane geometry are flat shapes and closed figures such as circles, squares, rectangles, rhombuses, etc. Three-dimensional shapes in solid geometry are the cube, cuboid, cone, sphere, and cylinder. Several of these shapes are familiar to us in daily life. For example, books have a cuboid shape, glasses have a cylindrical shape, traffic cones have a conical shape, etc. You will learn about different geometric shapes and their definitions in this article.

## Geometric Shapes: Definition

Objects can be represented by geometric shapes, which are geometrical figures. Three-dimensional shapes are sometimes two-dimensional, and sometimes two-dimensional. The two-dimensional figures lie only on the x- and y-axes, but 3D shapes lie on the x, y, and z axes. This is the height of the object on the z-axis. In geometry, different shapes are defined. We have previously discussed this in the introduction.

Any of these figures can be drawn or designed by starting with a line, a line segment, or a curve. We can generate different types of figures and shapes by arranging these lines in different ways, such as a triangle, a figure made up of connected segments of three lines, a Pentagon made up of five lines, and so on. But not all figures are complete figures.

## Types of Geometric Shapes

It is considered an open geometric shape when an object or a shape does not have both ends connected. Objects or shapes that are connected at both ends are defined as closed geometric shapes. There are two types of closed geometric shapes:

1. Geometric shapes in two dimensions: These are two-dimensional shapes with only x- and y-axes. They are flat, two-dimensional structures. Examples include triangles, squares, rectangles, etc.
2. Three-dimensional geometric shapes: These are 3D shapes that have an x-axis, y-axis, and z-axis. This is the height of the object on the z-axis. They are solid, three-dimensional structures. They may be cubes or cuboids, for example.

To draw any of these figures, we must start with a line, a curve, or a line segment. Thus, based on the number and arrangement of the lines, we can make various shapes and figures, for example, by joining four-line segments, a rectangle appears. By joining three-line segments, a triangle appears, and so on.
