The polygon is a Quadrilateral.
40 sides
If its a regular polygon then 180-interior angle and divide the answer into 360 which will give the number of sides of the polygon.
360/18 = 20 sides
The perimeter of a polygon is the sum of the length of each of its sides. If the polygon is a regular polygon the you can calculate the perimeter as [number of sides] *[the length of one side]
360/exterior angle = number of sides of a regular polygon
The polygon is a Quadrilateral.
It will have 10 equal sides
40 sides
If its a regular polygon then 180-interior angle and divide the answer into 360 which will give the number of sides of the polygon.
360/18 = 20 sides
The perimeter of a polygon is the sum of the length of each of its sides. If the polygon is a regular polygon the you can calculate the perimeter as [number of sides] *[the length of one side]
140
By dividing the number of its sides into 360 degrees
It would have 6 sides.
It will have 3 sides and it is an equilateral triangle
A polygon with each interior angle measuring 180 degrees is a regular octagon. In a regular octagon, all the sides are the same length and all the interior angles are the same. Therefore, since each interior angle is 180 degrees, the number of sides is 8. You can use the formula n - 2, where n is the number of sides, to find the number of sides for any regular polygon. In this case, n - 2 = 8 - 2 = 6. Since 6 is the number of sides, the polygon is an octagon.
