Interior Angles Polygon
This geometry video tutorial focuses on polygons and explains how to calculate the interior angle of a polygon such as hexagons pentagons and octagons.
Interior angles polygon. All the interior angles in a regular polygon are equal. Interior angles of a polygon intelligent practice. 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 angles or n 2 180 and then divide that sum by the number of sides or n.
An exterior angle of a polygon is an angle outside the polygon formed by one of its sides and the extension of an adjacent side. We know that the polygon can be classified into two different types namely. The interior and exterior angles together lie on a straight line.
Feel free to create and share an alternate version that worked well for your class following the guidance here. Interior angle of a polygon sum of interior angles number of sides. If it is a regular polygon all sides are equal all angles are equal shape sides sum of interior angles shape each angle.
If a polygon has 5 sides it will have 5 interior angles. An interior angle of a polygon is an angle inside the polygon at one of its vertices. Click to share on twitter opens in new window click to share on facebook opens in new window.
Or we can say that the angle measures at the interior part of a polygon are called the interior angle of a polygon. Since we know that the sum of interior angles in a triangle is 180 and if we subdivide a polygon into triangles then the sum of the interior angles in a polygon is the number of created triangles times 180. An interior angle of a polygon is an angle formed inside the two adjacent sides of a polygon.
A polygon will have the number of interior angles equal to the number of sides it has. For each vertex of a polygon. N n 2 180 n 2 180 n.
