WebArea of Polygon = n × Apothem 2 × tan ( π /n) When we don't know the Apothem, we can use the same formula but re-worked for Radius or for Side: Area of Polygon = ½ × n × Radius 2 × sin (2 × π /n) Area of Polygon = ¼ × n × Side 2 / tan ( π /n) A Table of Values WebA regular polygon has all angles equal and all sides equal, otherwise it is irregular Concave or Convex A convex polygon has no angles pointing inwards. More precisely, no internal angle can be more than 180°. If any …
WebMar 26, 2016 · To find the area of a regular polygon, you use an apothem — a segment that joins the polygon’s center to the midpoint of any side and that is perpendicular to that side … WebOct 3, 2024 · Draw the polygon whose angles you need to sum. The polygon can have any number of sides and can be regular or irregular. For example, you might want to find the sum of the interior angles of a hexagon, so you would draw a six-sided shape. 2 Choose one vertex. Label this vertex A. A vertex is a point where two sides of a polygon meet. 3
WebThe area of a regular polygon can be found using different methods, depending on the variables that are given. Commonly, one is given the side length \(s \), the apothem \(a\) (the distance from center to side--it is also the radius of the tangential incircle, often given as \(r\)), or the radius \(R\) (the distance from center to vertex--it is also the radius of the … WebNov 22, 2024 · Regular polygon formulas: sides, area, perimeter, angles.
