What is a rule for finding the number of diagnols for a polygon with N sides?
The rule is: 0.5*(N2-3N) = number of diagonals
What rule can be used to find number of diagonals that can be drawn from one vertex of regular polygon?
You can use the formula D=S-2 where D is the number of possible diagonals and S is the number of sides the polygon has.
How many diagonals does a dodecagon have?
12. There is actually a better answer and much larger answer than 12. The real answer is 54. Just because a dodecagon has 12 sides doesn't mean it has 12 diagonals because you can go either which way. To get a answer for this you can: 1. Multiply 12 and 9. You should get 108. 2. Then divid it by 2. You should get 54. That is correct: The general rule for a polygon with n sides is that it has n*(n-3)/2 diagonals.
What are the three rules of a polygon?
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.
What is the rule for a polygon?
Rule for PolygonThe rule/meaning for a polygon is; A shape that has to have three or more straight edges. They have to be connected. 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.What_is_the_Rule_for_a_polygon
How discover the slide rule?
Gunter
Is there a rule for the sum of angles outside of a polygon?
The exterior angles of any polygon add up to 360 degrees.
Who discover the Slide Rule?
John Napier .
What is the rule for the number lines of symmetry of any regular polygon?
Number of lines of symmetry = Number of sides of the regular polygon
A polygon will be dilated on a coordinate grid to create a smaller polygon. The polygon is dilated using the origin as center of dilation. Which rule could represent this dilation?
i can not tell you either
What is the rule for the sum of angles inside of a polygon?
It is: ('n'-2)*180 = sum of interior angles whereas 'n' is the number of sides of the polygon
Euler's rule for a polygon?
The rule applies to POLYHEDRA (3D shapes) not Polygons, which are 2D Faces + Vertices - Edges = 2
