360/exterior angle = number of sides of a regular polygon
If the polygon is a regular polygon then all interior angels are equal to 180-(360/no of sides of the polygon)
the formula is (n-2)x180/n where n is the number of sides the polygon has
The polygon is a Quadrilateral.
It will have 10 equal sides
We have the interior angle 144∘ . We can find the number of sides using the formula as follows. Thus, the polygon has 10 angles and 10 sides.
40 sides
360/18 = 20 sides
If it's a regular polygon: 360/number of sides = each exterior angle
I assume you mean a polygon inscribed in a circle. It is regular if all its sides and angles are equal.
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]
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.
The formula to find the sum of interior angles of a polygon is 180° × (n - 2), where n is the number of sides of the polygon.
