The formula is: Number of sides = 6.
The formula is: number of sides = number of vertices = 5.
Number of sides - 2
It is given by the formula (number of sides - 2) * 180 degrees.
It is the formula for double the interior angles of a polygon with n sides.
If it has 28 sides then it has 350 diagonals by using the formula 0.5(n^2 -3n) whereas 'n' means number of sides
The interior angle of a regular polygon with x sides is 180(x-2)/x. Rearranging the formula for x, the number of sides for a shape with y angles is 360/(180-y). From this formula, the number of sides is 40.
Euler
360/exterior angle = number of sides of a regular polygon
Formula: 0.5*(n2-3n) where n is the number of sides
The formula of the rectangle is multiplying the length and the width to get the area. You can add all the four sides so as to find the perimeter of the rectangle.
1/2*(n2-3n) where n is the number of sides of the polygon.
