One interior angle in a regular triacontagon is 168 degrees, meaning that one exterior angle would be 12°. The triacontagon is the largest regular polygon whose interior angle is the sum of the interior angles of smaller polygons: 168° is the sum of the interior angles of the equilateral triangle (60°) and the regular pentagon (108°).
The interior angle concept can be extended in a consistent way to crossed polygons such as star polygons by using the concept of directed angles.In general, the interior angle sum in degrees of any closed polygon, including crossed (self-intersecting) ones, is then given by 180(n–2k)°, where n is the number of vertices, and the strictly positive integer k is the number of total (360 ...
For a regular n-gon, the sum of the perpendicular distances from any interior point to the n sides is n times the apothem [4]: p. 72 (the apothem being the distance from the center to any side). This is a generalization of Viviani's theorem for the n = 3 case. [5] [6]
For each edge, the interior points are all on the same side of the line that the edge defines. The angle at each vertex contains all other vertices in its edges and interior. The polygon is the convex hull of its edges. Additional properties of convex polygons include: The intersection of two convex polygons is a convex polygon.
Exterior angle – The exterior angle is the supplementary angle to the interior angle. Tracing around a convex n-gon, the angle "turned" at a corner is the exterior or external angle. Tracing all the way around the polygon makes one full turn, so the sum of the exterior angles must be 360°. This argument can be generalized to concave simple ...
A Connecticut man who allegedly killed a woman and her infant son in November targeted the woman because she owed him $400 for renting a vehicle of his, arrest reports said on Monday.
The same is true for the geodesic center, a point in the polygon that minimizes the maximum length of its geodesic paths to all other points. [26] The visibility polygon of an interior point of a simple polygon, the points that are directly visible from the given point by line segments interior to the polygon, can be constructed in linear time ...
CHISINAU (Reuters) -A knife-edge majority of 50.17% voted "yes" in Moldova's pivotal referendum on joining the European Union, nearly final results showed on Monday, after President Maia Sandu ...
