If 'n' is the number of sides in a polygon with equal side length, then the number of sides is equivalent to (n-2)*180 degrees = total degrees in the polygon.
E.g.) A polygon is even-sided with 360 degrees in its interior. How many sides does it have?
Answer: (n-2)*180 = 360
n - 2 = 2
n = 4

Why do you use the number 2 to find the sum of the interior angle of a polygon?
It is used in the formula for finding the sum of the interior angles of a polygon:- (n-2)*180 = sum of interior angles whereas 'n' is the number of sides of the polygon
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 do you find the diagonals in a pentagon?
Use the formula: 0.5*(n2-3n) whereas 'n' is the number of sides of the polygon So: 0.5*(25-15) = 5 diagonals
What is the angle sum of a polygon with unknown sides?
The sum of the angles in a polygon with n sides is:180*(n - 2), where n is the number of sides.To find the measure of just one of the angles use the formula:180*(n - 2) / n

What fiqure would use 30 toothpicks as edges?
A 30-sided polygon is a tricontagon.
What are the degrees of the polygon?
To find the number of degrees in ANY polygon, you can use this formula: (x-2)180 x is the number of sides in your polygon EXAMPLE: A Hexagon: (6 sides-2)180= 720o I hope this helps :D

What's area formula of an irregular polygon?
Divide polygon into rectangles, then use area formula for rectangle: Area = (high a + high b) / 2 x length c If polygon contains triangle, then triangle can be considered as rectangle with one of its side length is close to zero.
