2D Shapes: Understanding the Basics

What are 2D Shapes?

2D shapes, also known as two-dimensional shapes, are geometric figures that have only two dimensions: length and width. They do not have a third dimension, which is depth or height. 2D shapes are flat and can be drawn on a piece of paper or a flat surface.

Types of 2D Shapes

There are several types of 2D shapes, including:


  • ** Rectangle**: A rectangle is a 2D shape with four sides, where all angles are right angles (90 degrees).
  • Square: A square is a special type of rectangle with all sides of equal length.
  • Rhombus: A rhombus is a quadrilateral with all sides of equal length, but not all angles are right angles.
  • Trapezoid: A trapezoid is a quadrilateral with two pairs of opposite sides, where one pair is parallel and the other pair is not.


  • Triangle: A triangle is a 2D shape with three sides and three angles.
  • Pentagon: A pentagon is a 2D shape with five sides and five angles.
  • Hexagon: A hexagon is a 2D shape with six sides and six angles.

Circles and Ellipses

  • Circle: A circle is a 2D shape with no beginning or end, where every point on the circle is equal distance from the center.
  • Ellipse: An ellipse is a 2D shape that is similar to a circle, but is oval in shape.

Properties of 2D Shapes

2D shapes have several properties, including:

  • Angles: The angles of a 2D shape are the corners or vertices where two sides meet.
  • Sides: The sides of a 2D shape are the lines that make up the shape.
  • Vertices: The vertices of a 2D shape are the points where two sides meet.
  • Symmetry: Some 2D shapes have symmetry, which means that one half of the shape is a mirror image of the other half.

Real-World Applications of 2D Shapes

2D shapes are all around us and have many real-world applications, including:

  • Architecture: Buildings and bridges use 2D shapes to create structural designs.
  • Art: Artists use 2D shapes to create paintings, drawings, and sculptures.
  • Design: Graphic designers use 2D shapes to create logos, icons, and other visual elements.
  • Engineering: Engineers use 2D shapes to design machines, mechanisms, and other devices.

In conclusion, 2D shapes are an essential part of mathematics and are used in many areas of our daily lives. Understanding the properties and types of 2D shapes can help us solve problems, create designs, and appreciate the beauty of art and architecture.
