- Shapes are outlines or the outer surface of objects. They can be classified as 2D shapes and 3D shapes. Two-dimensional shapes are measured in two dimensions, length and height. Three-dimensional shapes are measured in three dimensions, length, width and height.

Shapes can be classified into open and closed shapes. Closed geometric shapes can further be put into two broad categories, namely two-dimensional shapes and three-dimensional shapes. Here’s a list of 2-D or two-dimensional shapes with their names and pictures: Two-Dimensional Geometric Shapes.
In geometry, shapes are the forms of objects which have boundary lines, angles and surfaces. There are different types of 2d shapes and 3d shapes. Shapes are also classified with respect to their regularity or uniformity. A regular shape is usually symmetrical such as a square, circle, etc. Irregular shapes are asymmetrical.

In mathematics—namely geometry—and in real life, geometric shapes are two or three-dimensional figures that can be recognized and categorized based on a specific outline/boundary and other attributes including curves, lines, and angles.
A shape can be defined as the boundary or outline of an object which is made by combining curves, points, and line segments. Each shape has a name depending upon its structure. Learn different types of shapes along with the list of shapes with examples.
A shape is a graphical representation of an object's form or its external boundary, outline, or external surface. It is distinct from other object properties, such as color, texture, or material type. In geometry, shape excludes information about the object's position, size, orientation and chirality. [1] .
Nov 4, 2024 · A Guide For Teachers & Students. November 4, 2024 | 8 min read. Melanie Doppler. Shapes are a part of the geometry domain throughout the early elementary grades. Students learn how to define math shapes, learn the attributes of basic shapes, categorize math shapes by attribute and eventually learn to measure various math shapes.

Shapes can be classified according to their sizes or whether they are open and closed shapes. Open Shapes: Figures with line segments or curves that do not connect at a point are referred to as open shapes. Closed shape: Figures with connected line segments or curves are referred to as closed shapes.
