WebThe sum of internal angles for any (not complex) pentagon is 540°. Furthermore, if the shape is a regular polygon (all angles and length of sides are equal) then you can simply divide the sum of the internal angles by the number of sides to find each internal angle. 540 ÷ 5 = 108°. A regular pentagon therefore has five angles each equal to ... WebNov 26, 2024 · A regular polygon with each interior angle of 175 deg will have each exterior angle as 180–175 = 5 deg. Hence the number of sides in the regular polygon = 360/5 = 72 sides. … How to find the interior angle of a polygon?

WebJul 7, 2024 · A regular polygon with each interior angle of 175 deg will have each exterior angle as 180–175 = 5 deg. Hence the number of sides in the regular polygon = 360/5 = 72 sides. …. WebDec 31, 2024 · If the interior angle is 130° then the exterior angle will be 50°. The sum of the exterior angles is always 360° and we can use this fact to find the number of sides. 360° ÷ 50° = 7.2 sides. The number of sides has to be a natural number, so 7.2 is not possible, therefore 130° is not possible for the angles of a regular polygon. database of jee mains 2017

WebThe triacontagon is the largest regular polygon whose interior angle is the sum of the interior angles of smaller polygons: 168° is the sum of the interior angles of the equilateral triangle (60°) and the regular pentagon (108°). The area of a regular triacontagon is (with t = edge length) [1] The inradius of a regular triacontagon is. WebA regular polygon has all angles equal and all sides equal, otherwise it is irregular : Regular : Irregular . Concave or Convex. A convex polygon has no angles pointing inwards. More precisely, no internal angle can be more … WebOther & Older Versions of Applets in Chapter 1.
