The rule for a shape to be a polygon is it has to be a shape that has three or more straight edges, none of them can overlap, and they all have to be connected.
the first rule of a polygon is that it must have straight lines to devolope its sides. the second rule of a polygon is that it must be enclosed with no openings. the last rule of a polygon is that it has to have at least three sides.
0.5*(n2-3n) and n is the number of sides of the polygon
The exterior angles of any polygon add up to 360 degrees.
Number of lines of symmetry = Number of sides of the regular polygon
i can not tell you either
The rule is: 0.5*(N2-3N) = number of diagonals
It is: ('n'-2)*180 = sum of interior angles whereas 'n' is the number of sides of the polygon
If the vectors form a polygon, their sum is zero..
The rule applies to POLYHEDRA (3D shapes) not Polygons, which are 2D Faces + Vertices - Edges = 2
Yes and it is: ('n'-2)*180 = sum of interior angles whereas 'n' is the number of sides of the polygon
Since any polygon can be constructed from a combination of other polygons, I would call this rule a "trivial property of polygons".
(number of sides - 2)*180 = total sum of interior angles
