How Many Sides Does A Regular Polygon Have If One Exterior Angle Is 1 Now, the area of a triangle is half of the base times height, so: area of one triangle = base × height 2 = side × apothem 2. to get the area of the whole polygon, just add up the areas of all the little triangles ("n" of them): area of polygon = n × side × apothem 2. and since the perimeter is all the sides = n × side, we get:. Regular polygon calculator.
Exterior Angles Of A Polygon Definition Measuring Exterior Angles Of In order to find the measure of a single interior angle of a regular polygon (a polygon with sides of equal length and angles of equal measure) with n sides, we calculate the sum interior anglesor $$ (\red n 2) \cdot 180 $$ and then divide that sum by the number of sides or $$ \red n$$. The sum of interior angles of n sided polygon is. s = (n 2) x 180°. sum of exterior angles of any polygon is 360 degree. problem 1 : find the number of sides of a regular polygon whose each exterior angle measures 60°. solution : sum of all exterior angles = 360°. n × 60 = 360. n = 360 60. Solution: a regular polygon is one in which all the sides and angles are equal. the polygon with 8 equal sides is an octagon. the formula to find out the individual external angles of a polygon is given by, an exterior angle of a polygon = 360° number of sides of the polygon the number of sides of an octagon is 8.
