# Which polygon has no of sides diagonal?

## Which polygon has no of sides diagonal?

Pentagon is a diagonal having the number of diagonals equal to the number of sides.

## What is the rule of diagonals in polygons?

The number of diagonals in a polygon that can be drawn from any vertex in a polygon is three less than the number of sides. To find the total number of diagonals in a polygon, multiply the number of diagonals per vertex (n – 3) by the number of vertices, n, and divide by 2 (otherwise each diagonal is counted twice).

Do irregular polygons have diagonals?

Since the irregular polygons have the same number of vertices, and the number of diagonals depends only on the number of vertices, not the lengths of the sides, the number of diagonals would be exactly the same for irregular polygons as for regular polygons with the same number of sides.

Are diagonals equal in regular polygon?

Since all regular polygons have all angles of equal measure, to obtain to the measure of each angle in a polygon with vertices we can simply divide the sum of the measures of all interior angles by . As we already noticed, diagonals in a regular polygon do not intersect at one point.

### What polygon is not regular?

An irregular polygon is any polygon that is not a regular polygon. It can have sides of any length and each interior angle can be any measure. They can be convex or concave, but all concave polygons are irregular since the interior angles cannot all be the same.

### Do polygons have to have equal sides?

A polygon can have a certain number of sides, but the sides do not necessarily have to be the same length. Both of the polygons below are pentagons because they both have five angles and sides, but look at the differences.

What is not a type of polygon?

To be a polygon, a flat, closed shape must use only line segments to create its sides. So a circle or any shape that has a curve is not a polygon.

What are the maximum number of diagonals in a polygon?

2 diagonals. An octagon has. 20 diagonals. A polygon ‘s diagonals are line segments from one corner to another (but not the edges). The number of diagonals of an n-sided polygon is: n (n − 3) / 2.

#### How many connected sides does a polygon have?

Thus, a figure having many sides is called a polygon. Its accepted mathematical definition is any figure that has more than two sides and which forms a closed figure is called polygon. Hence, polygon can have three and many more but finite sides. A three-sided polygon is called a triangle. The four-sided quadrilateral is a polygon.

#### How many sides and angles does every polygon have?

The simplest polygon, the triangle, has three interior angles (and three exterior angles!) so it also has three sides . You can have polygons with so many sides, they appear to be circles even when they are not.

How do you find diagonals in a polygon?

The number of diagonals in a polygon that can be drawn from any vertex in a polygon is three less than the number of sides. To find the total number of diagonals in a polygon, multiply the number of diagonals per vertex (n – 3) by the number of vertices, n, and divide by 2 (otherwise each diagonal is counted twice).
