Polygons Exterior And Interior Angles
In this video i will take you through everything you need to know in order to answer basic questions about the angles of polygons.
Polygons exterior and interior angles. An interior angle of a polygon is an angle inside the polygon at one of its vertices. The sum of the measures of the exterior angles of a polygon one at each vertex is 360. All the interior angles in a regular polygon are equal.
The sum of the exterior angles of a polygon is 360. Angle q is an interior angle of quadrilateral quad. 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.
Polygons are 2 dimensional shapes with straight sides. I will be focusing on conv. Quadrilaterals are 2d shapes with four sides and angles.
The formula for calculating the size of an interior angle in a regular polygon is. The sum of interior angles div number of sides. The interior and exterior angles at each vertex of any polygon add up to 180.
