Is a Plane Shape and a Polygon the Same?

Have you ever wondered what the difference is between a plane shape and a polygon? You may have heard these terms used interchangeably, but there is actually a key difference between the two. In this article, we will explore what plane shapes and polygons are, and how they are alike and different. We will also look at some examples of each type of shape.

By the end of this article, you will have a solid understanding of the difference between plane shapes and polygons, and you will be able to identify each type of shape with confidence.

Is A Plane Shape And A Polygon The Same? Yes No
Both are two-dimensional shapes
Both have a finite number of sides
Both can be convex or concave
Plane shapes can be regular or irregular
Polygons can be regular or irregular

What is a Plane Shape?

A plane shape is a two-dimensional figure that has only length and width. It does not have any thickness. Plane shapes are also called 2D shapes. Some common examples of plane shapes include squares, rectangles, triangles, and circles.

Plane shapes can be classified into different types based on their properties. Some of the most common types of plane shapes include:

  • Quadrilaterals: Quadrilaterals are plane shapes with four sides. Some common examples of quadrilaterals include squares, rectangles, parallelograms, and trapezoids.
  • Triangles: Triangles are plane shapes with three sides. Some common examples of triangles include equilateral triangles, isosceles triangles, and scalene triangles.
  • Circles: Circles are plane shapes with a curved edge. The center of a circle is a point called the circumcenter. The radius of a circle is the distance from the center of the circle to any point on the edge of the circle.

Plane shapes are used in a variety of ways in everyday life. They are used to create objects such as buildings, furniture, and clothing. They are also used in mathematics and science to represent different concepts.

What is a Polygon?

A polygon is a plane figure with at least three sides and angles. The word “polygon” comes from the Greek words “poly” meaning “many” and “gon” meaning “angle”. Polygons are classified by the number of sides they have.

  • Triangles: Polygons with three sides are called triangles.
  • Quadrilaterals: Polygons with four sides are called quadrilaterals.
  • Pentagon: Polygons with five sides are called pentagons.
  • Hexagon: Polygons with six sides are called hexagons.
  • Heptagon: Polygons with seven sides are called heptagons.
  • Octagon: Polygons with eight sides are called octagons.
  • Nonagon: Polygons with nine sides are called nonagons.
  • Decagon: Polygons with ten sides are called decagons.
  • Dodecagon: Polygons with twelve sides are called dodecagons.

Polygons can be regular or irregular. A regular polygon is a polygon with all sides equal and all angles equal. An irregular polygon is a polygon with at least one side or angle that is not equal to the others.

Polygons are used in a variety of ways in everyday life. They are used to create shapes such as stars, flowers, and snowflakes. They are also used in mathematics and science to represent different concepts.

Plane shapes and polygons are both two-dimensional figures. However, there are some key differences between the two. Plane shapes are flat and have no thickness, while polygons have at least three sides and angles. Plane shapes can be classified into different types based on their properties, while polygons are classified by the number of sides they have. Both plane shapes and polygons are used in a variety of ways in everyday life and in mathematics and science.

Are Plane Shapes and Polygons the Same?

Plane shapes and polygons are both two-dimensional figures, but there are some key differences between them.

Plane shapes are any two-dimensional figure that can be drawn on a flat surface. This includes squares, rectangles, circles, triangles, and many other shapes.

Polygons are a specific type of plane shape that has at least three sides and angles. Polygons can be regular or irregular, and they can be convex or concave.

Here is a table that summarizes the key differences between plane shapes and polygons:

| Feature | Plane Shape | Polygon |
|—|—|—|
| Number of sides | At least 2 | At least 3 |
| Angles | Can have any number of angles | Must have at least 3 angles |
| Convex or concave | Can be either | Must be convex |

Plane shapes are often used in art and design, while polygons are often used in mathematics and geometry.

Examples of plane shapes include:

  • Squares
  • Rectangles
  • Circles
  • Triangles
  • Pentagons
  • Hexagons
  • Octagons
  • Nonagons
  • Decagons

Examples of polygons include:

  • Equilateral triangles
  • Isosceles triangles
  • Right triangles
  • Scalene triangles
  • Quadrilaterals
  • Pentagons
  • Hexagons
  • Octagons
  • Nonagons
  • Decagons

Examples of Plane Shapes and Polygons

Here are some examples of plane shapes and polygons:

Plane shapes:

  • A square is a plane shape with four equal sides and four right angles.
  • A rectangle is a plane shape with four sides, two of which are parallel and equal in length, and two of which are perpendicular to each other.
  • A circle is a plane shape with all points equidistant from a central point.
  • A triangle is a plane shape with three sides and three angles.

Polygons:

  • An equilateral triangle is a polygon with three equal sides and three equal angles.
  • An isosceles triangle is a polygon with two equal sides and two equal angles.
  • A right triangle is a polygon with one right angle.
  • A scalene triangle is a polygon with three unequal sides and three unequal angles.
  • A quadrilateral is a polygon with four sides.
  • A pentagon is a polygon with five sides.
  • A hexagon is a polygon with six sides.
  • An octagon is a polygon with eight sides.
  • A nonagon is a polygon with nine sides.
  • A decagon is a polygon with ten sides.

These are just a few examples of the many different types of plane shapes and polygons that exist.

Is a plane shape and a polygon the same?

No, a plane shape and a polygon are not the same. A plane shape is a two-dimensional figure that has no thickness, while a polygon is a closed, two-dimensional figure with at least three straight sides.

What are the different types of plane shapes?

There are four main types of plane shapes:

  • Triangles: Polygons with three sides.
  • Quadrilaterals: Polygons with four sides.
  • Pentagons: Polygons with five sides.
  • Hexagons: Polygons with six sides.

What are the different types of polygons?

There are many different types of polygons, each with its own unique properties. Some of the most common types of polygons include:

  • Regular polygons: Polygons with all sides equal in length and all angles equal in measure.
  • Irregular polygons: Polygons with at least one side that is not equal in length to any other side or at least one angle that is not equal to any other angle.
  • Convex polygons: Polygons in which all interior angles are less than 180 degrees.
  • Concave polygons: Polygons in which at least one interior angle is greater than 180 degrees.

How do you find the area of a polygon?

The area of a polygon can be found using the following formula:

“`
Area = 1 / 2 * s * n
“`

where:

  • s is the length of one side of the polygon.
  • n is the number of sides in the polygon.

For example, the area of a triangle with sides of length 3, 4, and 5 would be:

“`
Area = 1 / 2 * 3 * 4 = 6 square units
“`

How do you find the perimeter of a polygon?

The perimeter of a polygon can be found by adding the lengths of all of its sides. For example, the perimeter of a square with sides of length 4 would be:

“`
Perimeter = 4 * 4 = 16 units
“`

a plane shape and a polygon are not the same. A plane shape is a two-dimensional figure that has no thickness, while a polygon is a closed, two-dimensional figure with at least three straight sides. Plane shapes can be regular or irregular, while polygons can be convex or concave. Plane shapes can be classified by their number of sides, while polygons can be classified by their number of sides and angles. Plane shapes and polygons are both important geometric figures that have a variety of applications in the real world.
