# Geometric Shapes Definition

Geometric figures are closed shapes made by using lines, points as well as circles, curves, and circles. These shapes are visible everywhere we look.

A few of the geometric shapes examples are rectangle, circle triangular, etc. Pizzas are circular with slices that are triangular. The same is true for windows and doors. can be considered as rectangles. A regular shape is one that has all sides being equal. For instance, a rectangular or regular hexagon. These irregular shapes have sides of various sizes. For example, a scalene triangle.

## A few of the most sought-after designs are explained in the following:

1. ### Rectangle

Rectangular is the form created by connecting four points on four distinct lines. When forming a rectangular shape, the opposing edges are parallel to each other and equally in length. All angles of the rectangle have a right angle. The main difference between the two can be seen in the fact that, within a rectangle two line segments that are parallel to each other have a greater length than the two other In the square, all lines are equal in length.

Examples of rectangular objects include mobile screens, laptop screens, etc.

### 2. Square

An square can be described as a quadrilateral geometric shape made by connecting four line segments that are equal in length. Like a rectangle the line segments that form the square are at an angle to each and each other. Some examples of square objects include Rubik’s Cube dice as well as chess board.

### 3. Circle

The circle can be described as a geometrical shape that is not made of straight lines. It is possible to conclude the circle to be composed of non-countable points located within the same distance of its center.

Circular objects include complete pizzas as well as wheels.

### 4. Triangle

A triangle is composed of three line segments that are connected. It is a complicated geometrical figure because it could have different angles and dimensions.

Triangular objects include pizza slices as well as nachos, birthday caps and more.

The name of a triangle is based on the angles as well as the size of its sides. For instance, if two lines of a triangle create an angle of right angles and are referred to as the right triangle. This is how it looks:

Any triangle that has angles of less than 90 degrees are referred to as an acute-angled triangular. In the same way, a triangle that has one angle that is greater than 90 degrees can be known as an obtuse-angled one. A triangle that is equiangular has every interior angle that are 60 degrees or more and all sides are equally long. See the figure below to get more understanding.

#### Real-life Applications of Geometric Shapes The study of geometry is of space and shape. It aids us in understanding the mathematical concepts of other mathematicians as well as practical applications. Geometry is a useful tool for making bridges, structures as well as cars and clothing. The concepts of geometry can also be applied to other areas of mathematics like trigonometry and calculus.

### Here are a few of the applications that are real-world:

squaresSquares are found throughout nature. including crystals with a square shape. They are also utilized in art. The famous painting of Piet Mondrian, titled “Composition with Red, Blue and Yellow” is an excellent example.

Rectangles Many made by humans, such as TVs books, computers, and even TV monitors have a rectangular shape. There are numerous examples in real life of rectangles, including coins, mobile phones, and book covers.

Circles The circle can be observed everywhere from the pizzas we eat to the faces of the clock.

Triangles There are triangular shapes in a variety of places. The majority of roofs feature triangular shapes known as gables. Triangles are a great way to aid in the construction of bridges and even buildings. There are chips that have the shape of triangles.

Ovals/Ellipses An ellipse or oval is an elongated circular (egg-like form) with a length that is more than the width.

## Three-dimensional shapes are a few examples

Three-dimensional shapes are composed of vertices and lines that connect the vertices, as well as faces that are enclosed through these lines. They are defined by their length, breadth and height, and take up a certain amount of space. For many 3D shapes, the faces have two dimensions. Some three-dimensional shapes are curved.

#### The three-dimensional most important shapes are:

• Cube: Rubik’s Cube Sugar cube
• Cone Ice Cream Cone, Pyramid
• Cuboid A timber rectangular wood box matchbox
• Cylinder A bathroom roll or a soda container

## Solved Examples

##### Example 1 How many sides does decagons have?

Solution A decagon has 10 sides and 10 vertices.

##### Example 2 What is a triangle that has only two sides equal?

Solution A triangle that has just two equal sides is known as an isosceles triangular.

##### Solution Cones are an three-dimensional shape. ## Practice Problems

1. A square is characterized by _____.
Two equal sides
Four equal sides.
Four unequal sides
None of these
2. The distance that extends from to the centre of a circle up to the outermost edge is known as the _____________.
curve
Diameter
chord
3. A cube is a ____________.
One-dimensional shape
Three-dimensional shape
Two-dimensional Shape
None of these
4. Equilateral triangles are _______.
an open shape
an irregular shape
A regular shape
A closed curve

## Conclusion

Geometric shapes are a part of our everyday life. For students, they aid in the formation of more complicated concepts like spatial relations.

#### What’s the most basic geometric figures? The most basic geometric shapes include circle or square, rectangle or triangle, for example. These shapes can be further placed in various combinations.

#### What is the process by which geometric shapes are created?

Geometric shapes are made by lines, points or curves. The key is to keep in mind that these shapes have to be mathematically defined. If a form cannot be described mathematically, it isn’t geometric.

#### What are some examples of shapes that aren’t geometric?

The shapes that are not geometric are found in nature. For example, pebbles, rivers, etc.

#### How do we define an area of polygon?

A polygon is a form comprised of straight lines, but without curves. It is not a shape with open sides. “Polygon” is an umbrella term that refers to various shapes, such as triangles, squares, and rectangles. Previous
