Whether you’re a student, an artist, or simply curious about the world, knowing the names of different shapes can be both practical and fascinating. With this useful list, we will explore various shapes and their names, and provide examples to help you better understand and appreciate the diverse range of shapes that exist.
So, let’s dive into the world of shapes and expand our knowledge together.
What is shape meaning?
Shape meaning refers to the symbolism or significance associated with different shapes. In various cultures and contexts, different shapes can hold specific meanings or convey certain messages. For example, a circle often represents unity, eternity, or perfection, while a triangle can symbolize stability, harmony, or balance.
The interpretation of shape meaning can vary based on cultural, religious, or personal beliefs, and it is often used in art, design, and symbolism to convey deeper messages or evoke specific emotions.

There are various kinds of shapes, including:

 Geometric shapes
 Organic shapes

 Symmetrical shapes
 Irregular shapes
 Curved shapes
 Polygons
 Open shapes
 Regular shapes
 Irregular polygons
1. Geometric shapes:
These basic shapes have defined properties, such as squares, circles, triangles, rectangles, and polygons. They are often used in mathematics and design.

 Circle: a round shape with no sides or angles. Examples: wheels, coins.
 Square: a shape with four equal sides and four right angles. Examples: tiles, and picture frames.
 Triangle: a shape with three sides and three angles. Examples: road signs, pyramids.
 Rectangle: a shape with four sides and four right angles, where opposite sides are equal in length. Examples: books, doors.
 Oval: a stretchedout circle with curved sides. Examples: eggs, footballs.
 Pentagon: a shape with five sides and five angles. Examples: military badges, and stars.
 Hexagon: a shape with six sides and six angles. Examples: honeycomb, stop signs.
2. Organic shapes:
These shapes are irregular and freeform, often found in nature, such as clouds, leaves, or waves. They do not have welldefined boundaries or angles.

 Circles: Circles are a common type of organic shape that is smooth, curved, and freeflowing. They are often associated with unity, harmony, and completeness.
 Ovals: Ovals are elongated organic shapes that resemble stretched circles. They convey a sense of movement and elegance.
 Curved lines: Curved lines are organic shapes that are fluid and flowing. They can be found in nature, such as in the shape of waves or the curve of a flower petal. They often evoke a sense of grace and beauty.
 Amorphous shapes: Amorphous shapes are irregular and undefined, lacking distinct edges or corners. They can be found in natural elements like clouds, puddles, or tree branches. Amorphous shapes often create a sense of randomness or unpredictability.
 Spheres: Spheres are threedimensional organic shapes that are round and voluminous. They are often associated with unity, perfection, and balance.
 Organic patterns: Organic patterns are repetitive arrangements of organic shapes, such as leaves, flowers, or waves. They can create a sense of rhythm, movement, and natural beauty.
 Freeform shapes: Freeform shapes are irregular and asymmetrical, lacking defined boundaries or geometric proportions. They can be found in abstract art or natural formations like rocks or tree branches. Freeform shapes often evoke a sense of uniqueness and creativity.
3. 3D shapes:
These shapes have depth and volume, unlike 2D shapes which are flat. Examples include cubes, spheres, pyramids, and cylinders.

 Cube: A cube is a threedimensional shape with six equal square faces. All angles of a cube are right angles, and all sides are equal in length.
 Sphere: A sphere is a perfectly round threedimensional shape. It is completely symmetrical and all points on its surface are equidistant from its centre.
 Cylinder: A cylinder is a threedimensional shape with two parallel circular bases connected by a curved surface. It has two flat faces and one curved face.
 Cone: A cone is a threedimensional shape with a circular base and a pointed top. It has one flat face and one curved face.
 Pyramid: A pyramid is a threedimensional shape with a polygonal base and triangular faces that meet at a common vertex. The number of sides on the base determines the name of the pyramid (e.g., a triangular pyramid has a triangular base).
 Rectangular Prism: A rectangular prism is a threedimensional shape with six rectangular faces. It has three pairs of equal opposite faces.
 Tetrahedron: A tetrahedron is a threedimensional shape with four triangular faces. It has four vertices and six edges.
Note that some threedimensional shapes could occur in twodimensional forms. Also, abstract shapes refer to the shapes that have no regular shape where you can count the number of angles and sides. On the other hand, there are some twodimensional shapes that could become threedimensional shapes as well, like a star for example! ^{1}
4. Symmetrical shapes:
These shapes have a balance and mirrorimage quality, where one half is the same as the other when divided by a line or point of symmetry.

 Square: A square is a symmetrical shape with four equal sides and four equal angles. It has a rotational symmetry of 90 degrees.
 Rectangle: A rectangle is a symmetrical shape with four right angles and opposite sides that are equal in length. It has a rotational symmetry of 180 degrees.
 Equilateral Triangle: An equilateral triangle is a symmetrical shape with three equal sides and three equal angles. It has a rotational symmetry of 120 degrees.
 Circle: A circle is a symmetrical shape with a curved boundary that is equidistant from the centre point. It has a rotational symmetry of 360 degrees.
 Regular Hexagon: A regular hexagon is a symmetrical shape with six equal sides and six equal angles. It has a rotational symmetry of 60 degrees.
 Regular Pentagon: A regular pentagon is a symmetrical shape with five equal sides and five equal angles. It has a rotational symmetry of 72 degrees.
 Regular Octagon: A regular octagon is a symmetrical shape with eight equal sides and eight equal angles. It has a rotational symmetry of 45 degrees.
5. Irregular shapes:
These shapes do not have a specific or regular form, often characterized by uneven or unpredictable contours.

 Polygon: A polygon is a closed shape with straight sides and angles. It can have any number of sides, making it irregular if it does not meet the criteria of a regular polygon (equal sides and angles).
 Quadrilateral: A quadrilateral is a foursided polygon. Irregular quadrilaterals have sides of different lengths and angles that are not equal.
 Pentagon: A pentagon is a fivesided polygon. Irregular pentagons have sides of different lengths and angles that are not equal.
 Hexagon: A hexagon is a sixsided polygon. Irregular hexagons have sides of different lengths and angles that are not equal.

6. Curved shapes:
These shapes have smooth, rounded lines and contours, without any sharp angles.

 Circle: A closed curve where all points are equidistant from the center.
 Oval: A stretched circle that is elongated in one direction.
 Ellipse: A closed curve that is similar to an oval, but with two distinct centers.
