linesegmentA simple polygon P is said to be weakly extrenally visible from a line segment L if it lies outside P and for every point p on the boundary of P there is a point q on L such that no point in the interior of lies inside P. In this paper, a linear time algorithm is ...
A diagonal is a line segment that connects two vertices that are not adjacent to a polygon. The segment that connects two adjacent vertices is called a side (or edge). What is the diagonal formula? The formula to find the number of the diagonals of a polygon is n(n-3)/2. Where n ...
Now, in order to find the area of a polygon that has not a regular defined shape, we need to first split it into triangles, squares, trapezium, etc. The purpose is to visualize the given figure as a combination of geometries for which we already know how to calculate the area. Another...

{include ad_line.html %} Let's talk about a diagonal for a minute. What is adiagonalanyway? A diagonal is a line segment connecting twononconsecutivevertices of the polygon. It's all the lines between points in a polygon if you don't count those that are also sides of the polygon. ...

This is the case with concave and convex polygons as well. A polygon is said to be convex if any two interior points determine a segment of line totally contained in the polygon. Otherwise, the polygon is concave. Figure 3. Convex quadrilateral on the left and concave hexagon on the ...
