The area of an n-sided regular polygon with length of side t is equal to:
nt2 / (4 tan(180 / n))
Taking a simple example, if a square (n = 4) has sides of 2 inches (t = 2):
4 x 22 / (4 tan (180 / 4)) = 4
Therefore, the area of a square with 2 inch sides is 4 inches. Upon completion of the sum, don't forget to include the units of measure at the end.
The area of a four-sided polygon is base times height.
An n sided polygon has n*(n-3)/2 diagonals.
An n-sided polygon or n-gon, just like it sounds, has n sides. For example, a 13-sided polygon has 13 sides. A 24-gon has 24 sides.
The sum of the internal angles of a n-sided polygon is (n-2) x 180o. For a 17-sided polygon, n = 17 and the sum of the angles is (17-2) x 180o = 2700o
There are: (n-2)
The name for a polygon with n sided is a n-gon.
interior angle of an n-sided polygon = (180(n-2)/n)°interior angle of a 24-sided polygon = (180x22/24)° = 165°
The name of a 654 sided polygon is: "n-gon".
The area of a four-sided polygon is base times height.
18. If a polygon has n sides, then it has n-2 triangles.There are 18 triangles in a 20 sided polygon.
For a regular n-sided polygon with sides of length s, the formula is: A = (n*s^2) / (4*tan(180/n))
n
n-gon
Sum of interior angles of an n-sided polygon = (n-2) x 180Sum of one interior angle of an n-sided polygon = (n-2) x 180 then divide by n.
An n sided polygon has n*(n-3)/2 diagonals.
A 4-sided polygon has 2 diagonals. A 5-sided polygon, 5. 6-sided, 9. By induction, an n-sided polygon has 'n*(n-3)/2' diagonals. "n" is how many sides a shape has. so, (7)*(7-3)/2 now we have, 7*4/2 so, 28/2 = 14 Therefore, a 7-sided polygon would have 14 diagonals.
N-gon is the name of 13-20 sided polygon.
