Oct 7, 2024 · A diagonal in a polygon is a line segment that connects two non-consecutive vertices. For example, in a square, the line segment connecting two opposite corners is a diagonal. Diagonals play a crucial role in determining the number of triangles that can be formed within a polygon.

A Polygon is a closed figure made up of line segments (not curves) in a two-dimensional plane. Polygon is the combination of two words, i.e. poly (means many) and gon (means sides). A minimum of three line segments is required to connect end to end, to make a closed figure. Thus a polygon with a minimum of three sides is known as Triangle and it is...
By definition, we know that the polygon is made up of line segments. Below are the shapes of some polygons that are enclosed by the different number of line segments.
Depending on the sides and angles, the polygons are classified into different types, namely: 1. Regular Polygon 2. Irregular Polygon 3. Convex Polygon 4. Concave polygon
As we know, any polygon has as many vertices as it has sides. Each corner has a certain measure of angles. These angles are categorized into two types namely interior angles andexterior angles of a polygon.
The properties of polygons are based on their sides and angles. 1. The sum of all the interior angles of an n-sided polygon is (n – 2) × 180°. 2. The number of diagonals in a polygon with n sides = n(n – 3)/2 3. The number of triangles formed by joining the diagonals from one corner of a polygon = n – 2 4. The measure of each interior angle of n-si...
The area and perimeter of different polygons are based on the sides. Area:Area is defined as the region covered by a polygon in a two-dimensional plane. Perimeter: Perimeter of a polygon is the total distance covered by the sides of a polygon. The formulas of area and perimeter for different polygons are given below: Let us see one of the frequentl...
A triangle is the simplest form of the polygon that has three sides and three vertices. The triangles are also classified into different types, based on the sides and angles.
A Quadrilateral is a polygon having a number of sides equal to four. That means a polygon is formed by enclosing four line segments such that they meet at each other at corners/vertices to make 4 angles. Like triangles, a quadrilateral is also classified with different types: 1. Square 2. Rectangle 3. Parallelogram 4. Rhombus 5. Trapezium The below...
A three-dimensional shape is a solid object that is formed by a combination of polygons and 2d shapes. Some of the 3d shapeswhich we can observe in real-life are: 1. These are the shapes that can be projected on a piece of paper but cannot be drawn on paper. These shapes are known as solids. 1. 3-D shapes have faces as the distinguishing feature. T...

Closed Shapes in Geometry. A triangle is a closed figure with 3 sides and 3 vertices. A circle is a closed shape with no sides, no vertices, and one face. A quadrilateral is a closed shape with 4 sides and 4 vertices. Examples of a quadrilateral are square, rectangle, rhombus, parallelogram, trapezium, etc. A pentagon is a closed shape with 5 ...
