Names of Basic Shapes and Their Definitions with Image

Understanding all shapes names and characteristics is fundamental in both mathematics and everyday life. From the simple circle to the complex hexagon, each shape has distinct properties that define its structure and uses. This page will guide you through the most common geometric shapes, offering clear definitions and practical examples to help you recognise and understand them better. Whether you're a student, educator, or simply curious about geometry, this comprehensive guide will enhance your knowledge of shapes and their applications. Explore our detailed explanations and learn how these fundamental shapes form the building blocks of more complex geometric concepts.

Shapes and Their Names

Everywhere we see objects of different shapes and each shape holds significance and certain properties. So, if you look at a chocolate box, it looks like a rectangle and each piece of chocolate seems square in shape. So, what properties does each shape have and how do identify each shape and distinguish between these shapes, this is a major concern.

Now, let us go through various shapes and understand tips to distinguish between them with the help of properties.

Circle

• Definition: A round plane figure whose boundary (the circumference) is equidistant from the centre.

• Properties:

• No corners or edges.

• All points on the circumference are the same distance from the centre.

• The boundary is smooth and curved.

Square

• Definition: A four-sided polygon (quadrilateral) with equal-length sides and four right angles.

• Properties:

• All sides are of equal length.

• All internal angles are 90 degrees.

• The opposite sides are parallel.

Triangle

• Definition: A three-sided polygon with three corners or vertices.

• Properties:

• The sum of the internal angles is always 180 degrees.

• Can be classified as equilateral (all sides equal), isosceles (two sides equal), or scalene (all sides different).

• Has three edges.

Rectangle

• Definition: A four-sided polygon (quadrilateral) with opposite sides equal in length and four right angles.

• Properties:

• Opposite sides are parallel and equal in length.

• All internal angles are 90 degrees.

• The sum of the internal angles is 360 degrees.

Oval

• Definition: An elongated circle or an elliptical shape, with a smooth, curved boundary.

• Properties:

• No corners or edges.

• The shape is symmetric along its long axis.

• It has two focal points.

Pentagon

• Definition: A five-sided polygon with five corners or vertices.

• Properties:

• The sum of the internal angles is 540 degrees.

• Can be regular (all sides and angles equal) or irregular.

• Has five edges.

Hexagon

• Definition: A six-sided polygon with six corners or vertices.

• Properties:

• The sum of the internal angles is 720 degrees.

• Can be regular (all sides and angles equal) or irregular.

• Often seen in nature, such as in honeycombs.

Octagon

• Definition: An eight-sided polygon with eight corners or vertices.

• Properties:

• The sum of the internal angles is 1080 degrees.

• Can be regular (all sides and angles equal) or irregular.

• Has eight edges.

Different Shapes for Kids

Shape	Name of the Shape	Property(s)
	Triangle	A shape having three sides or edges. Other thighs about a triangle: There are three types of triangles: A triangle having its all sides equal is called an equilateral triangle. A triangle having its two sides equal is called an isosceles triangle. However, a triangle shown below has one side standing straight over the other side, in this case, two sides are equal and we call such a triangle a right-angled isosceles triangle. A triangle having all its sides different is called a scalene triangle.
	square	All four sides equal
	Rectangle	Two parallel sides are equal to each other and the other two parallel sides are equal to each other.
	Circle	No sides Have a radius
	Diamond	It has four sides just like a square
	Heart shape	A heart shape with no sides
	Arrow	The left-headed arrow
	A star
