Measures Of Interior Angles Of Polygons The interior angle of a regular polygon is 135⁰. work out the number of sides of the polygon. solution : = (n 2) × 180 n 135n 180 = n 2 27n 36 = n 2 2 = n 3n 4 2 = 4n 3n 4 2 = n 4 n 4 = 2 n = 2 (4) n = so, the number of sides of the regular polygon is 8. problem 3 : the sum of the interior angles in a polygon is 7380⁰. calculate the. Interior angles of a polygon |formulas.
Regular Polygons Chart Interior angles of polygons. Regular polygon calculator. A regular polygon 👉 learn how to determine the number of sides of a regular polygon. a polygon is a plane shape bounded by a finite chain of straight lines. Interior angle = 180(n 2) n, where n is the number of sides of the polygon. explanation: let us find the number of sides a regular polygon with an interior angle of 108°. ⇒ 180(n−2) n = 108° ⇒ 180n − 360 = 108n. ⇒ 72n = 360. ⇒ n = 5. so, a regular polygon with an interior angle of 108° would have 5 sides.

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:. 6 sides – irregular hexagon. find the sum of interior angles for any polygon s given. show step. sum of interior angles = (n – 2) × 180°. sum of interior angles for a hexagon = (6 – 2) × 180°. sum of interior angles for a hexagon = 720°. identify what the question is asking you to find.
