The number of diagonals for a shape with x sides is (x²-3x)/2
The number of sides is x
You want to know if x is ever less than (x²-3x)/2 or else (x²-3x)/2 - x > 0
(x² - 3x) / 2 - x > 0
(x² - 3x)/2 - (2x)/x > 0
x² - 3x - 2x > 0
x² - 5x > 0
x(x-5)>0
This only true if x<0 or x>5, and since a polygon cannot have less than 2 sides, x<0 is meaningless.
This means that if x<5 then the number of diagonals is less than the number of sides, equal for x=5, and more for x>5. ■

Are there diagonals in an Heptagon?
Yes. Any polygon with four or more sides has diagonals. However, a triangle does not.
How many diagonals does a 2 sided polygon have?
There is no such polygon because a polygon must have at least 3 sides or more.
Which shapes have more than two diagonals?
Any polygon with more than 4 sides.
What forms within a polygon shape?
Interior angles and if it has more than 3 sides also diagonals
Can a regular polygon with more than 6 sides ever tessellate?
No because as the polygon gets smaller the angles and sides get biggerso they can't tessellate by themselves.

How could you explain a polygon has more sides than angles?
I'd have to see one first. So far, no polygon I've ever seen had more sides than angles.
A polygon with five or more sides?
A polygon with 5 or more sides can be a stop sign it has 8 sides.
Does a cube have more sides than a polygon?
" A polygon is a closed figure bounded by three or more than three sides." A cube has twelve sides whereas a polygon has more than two sides. Since it is not mentioned which polygon we are talking about we can't tell if cube has more sides.
How many more sides does a polygon have than a octagon?
an octagon is a polygon. an octagon has 8 sides. a polygon is a shape with closed sides.
Does a polygon usually have more sides or more angels?
Any polygon has the same number of angles as its sides.
Can a dodecagon tessellate?
No, there is no polygon with 7 or more sides can tessellate.
Must a polygon have more than three sides?
A polygon must have 3 or more sides as with a triangle for example
