Intersection points and diagonals |
2013-09-11 |
|
Kenneth pose la question : I was wondering, is there a relationship between the number of sides of a regular n-gon and the number of times its diagonals intersect?
Ie:
4 sides=1 intersect (center, diagonals form an 'X' )
5 sides=5 intersects (diagonals form a star)
6 sides=13 intersects
And so on. Chris Fisher lui répond. |

Irregular polygon and Circle that Intersects All Sides |
2008-08-20 |
|
Xetro pose la question : Hi,
Suppose you have an irregular polygon(convex or concave) with n > 3 sides.
The question is - Find some circle that will cut(in limiting case - touch) all the sides of that polygon.
It doesnt matter how many times it cuts the side(1 or 2), it just have to cut or touch it.
How to find such a circle? or how to decide if such circle even exists?
What if those segments do not form a polygon but are some arbitrary segments ?
Really want to know how to do it................
Thanks a lot..
Regards,
Xetro Janice Cotcher lui répond. |

The centroid of a polygon |
2007-12-29 |
|
David pose la question : I am playing around with an idea. I've read previous answers to questions
(using surveyor calculation methods) related to finding the area of an irregular
shape parcel of land (or irregular polygon). Is there a formula or method for
calculating the centroid (mid-point) for this type of polygon. I've seen plenty
of methods for calculating the mid-point for a triangle or regular shape poloygon
but few for an irregular shape polygon such as a parcel of land. Thanks... Harley Weston lui répond. |
