## How do you make an N sided polygon?

How to draw a n sided regular polygon in cartesian coordinates?

- pick an angle to start from a radius and a center point.
- somehow calculate the x,y position at that distance from the center(how?)
- divide 360 by the number of sides, move that distance and draw the next line from the first x,y point.

**What are the 12 types of polygon?**

They are:

- Regular Polygons.
- Irregular Polygons.
- Concave Polygons.
- Convex Polygons.
- Trigons.
- Quadrilateral Polygons.
- Pentagon Polygons.
- Hexagon Polygons.

### What is the formula for polygons?

Polygon Formula The sum of interior angles of a polygon with “n” sides =180°(n-2) Number of diagonals of a “n-sided” polygon = [n(n-3)]/2. The measure of interior angles of a regular n-sided polygon = [(n-2)180°]/n.

**What is the condition to make a polygon?**

A polygon is a flat, two-dimensional (2D) shape with straight sides that is fully closed (all the sides are joined up). The sides must be straight. Polygons may have any number of sides. A shape with curved sides is not a polygon.

#### What is a N-sided polygon?

An n-gon is a polygon with n sides; for example, a triangle is a 3-gon. A simple polygon is one which does not intersect itself. A polygon is a 2-dimensional example of the more general polytope in any number of dimensions.

**How many sides does a n-gon have?**

Definition of a Polygon

Shape | # of Sides |
---|---|

Octagon | 8 |

Nonagon | 9 |

Decagon | 10 |

n-gon | n sides |

## What is polygon BYJU’s?

A polygon is a two-dimensional geometric figure that has a finite number of sides. The sides of a polygon are made of straight line segments connected to each other end to end. Thus, the line segments of a polygon are called sides or edges.

**What are the 20 polygons?**

Polygons: How Many Sides?

3 | triangle, trigon |
---|---|

17 | heptadecagon |

18 | octadecagon |

19 | enneadecagon |

20 | icosagon |

### How many sides a polygon has formula?

Answer: To find the number of sides of a polygon when given the sum of interior angles, we use the formula: Sum of interior angles = (n – 2) × 180, where n is the number of sides.

**What is N-sided polygon?**

#### How do you find the angle of an N-sided polygon?

The sum of the interior angles, in degrees, of a regular polygon is given by the formula 180(n – 2), where n is the number of sides.

**How many total sticks of length 11 can be made?**

Note 2: Discarded part can’t be used again for making sticks such that if a stick of length 11 is given we can break it into 5 and 6 of length pieces then we have to discard one of the pieces which can’t be used further. by breaking stick of length 11 into [5, 3, 3] pieces therefore total sticks will be 3.

## How do you find the number of sticks of the same length?

Approach: Approach to solve this problem is to sort the array and then find number of minimum length sticks that are of same length while traversing and update the sum accordingly at each step and in the end return the sum. Time Complexity: O (Nlog (N)) where N is the number of sticks. Add the count of non-zero sticks to the resultant stick.

**How to find the sum of sticks left after each iteration?**

Given N number of sticks of varying lengths in an array arr, the task is to determine the sum of the count of sticks that are left after each iteration. At each iteration, cut the length of the shortest stick from remaining sticks.

### What is the optimal time complexity of print triangulation?

Time complexity of the above dynamic programming solution is O (n 3 ). Extend the above solution to print triangulation also. For the above example, the optimal triangulation is 0 3 4, 0 1 3, and 1 2 3. Attention reader! Don’t stop learning now.
