Geometric Shapes

Geometric shapes can be interpreted as diagrams or pictures that exemplify the structures we use to observe in our day-to-day lives. The geometric shapes comprise curves and surfaces. These shapes have distinct internal regions, external regions, and a distinct barrier. In our actual lives too, we come in contact with a lot many geometrical shapes.

Geometrical Shapes in Geometry

In geometry, the students get to learn about geometrical shapes. There are two major categories of any geometric shape. The first one is the regular geometric shape and the other one is irregular geometric shape.
The geometric shapes can be of open shape or also even sealed shape. They can be of various sizes and configurations.

  • All of these shapes have their own unique and special properties and characteristics.
  • All of the geometric shapes are made up by assembling the points and lines. All of these shapes have definite
  • names that define them.
  • The two-dimensional geometric figures have two axes, one of them is the x-axis and the other one is the y- axis.
  • The three-dimensional figures have three axes, one of them is the x-axis, another one is the y-axis and the third
  • one is the z-axis.
  • A few examples of two-dimensional geometric figures are triangle, circle, square, rectangle, and several extras.
  • A few examples of three-dimensional geometric figures are cube, cuboid, and several extras.

Examples of Geometric Shapes

Here are a few examples of geometric shapes:

  • Circles
  • Triangles
  • Hexagons
  • Pentagons
  • Squares
  • Rectangles
  • Kites
  • Trapeziums
  • Parallelograms

Regular Geometric Shapes

The regular geometric shapes are the figures that consist of walls that have identical lengths and the interior angles are also the same as each other.


A few examples to understand better about the regular geometric shapes are:

  • Circles
  • Triangles
  • Squares
  • Polygon

Irregular Geometric Shapes

The irregular geometric shapes are the structures that do not consist of any identical sides or walls. The lengths of all the walls in these types of structures are very distinct. They also do not consist of any identical angles in them.
To discover the total area of an irregular geometric shape, one has to find the total amount of the area of the Polygon.


A few examples of the irregular geometric shapes to understand satisfactorily, are:

  • Rectangles
  • Kite
  • Irregular Quadrilateral

Perimeter of the Geometrical Shapes

Here are a few geometrical shapes with the formulas to get the perimeter.

  • Triangles – a+b+c (The sum of all the barriers).
  • Rectangles – 2*(length of the first set of parallel sides + width of a second set of the parallel sides)
  • 2* (length + width)
  • Square – 4* length of a wall
  • Trapezoid – the sum of all the sides, a+b+c+d
  • Kite – 2*(height of the first pair)+ 2* ( height of the second one)
  • Rhombus – 4* size of a one side
  • Hexagon – 6* size of a one side


A tetrahedron is a two-dimensional geometrical shape. A tetrahedron has four looks of triangular shapes. In all those four triangular faces, one of them is distinguished as the base of the tetrahedron. Rest all of the three triangular faces are in the shape of a pyramid.
A tetrahedron is also recognized as a triangle pyramid. A tetrahedron is also recognized as a polyhedron. This special geometrical shape consists of four faces together with four vertices.

Regular Tetrahedron

There is a regular tetrahedron. This shape has all four triangles equal. That means all four triangles are equilateral triangles. In a regular tetrahedron, the measurement of the internal angles is sixty degrees.
A tetrahedron figure is deprived of any parallel faces as other geometrical figures. There are six planes for symmetry in a tetrahedron.
