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
To find the number of sides of a regular polygon, you can use the formula: Number of sides = 360 degrees ÷ Measure of each interior angle. In this case, if one interior angle is 108 degrees, the regular polygon has 360 ÷ 108 = 3.33 sides. Since a polygon cannot have a fractional number of sides, we round down to the nearest whole number. Therefore, the regular polygon has 3 sides, which makes it an equilateral triangle.
360/exterior angle = number of sides of a regular polygon
The polygon is a Quadrilateral.
It will have 10 equal sides
40 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
