sum exterior angles polygon The angles of a regular polygon are equivalent and their sides are as well The sum of the exterior angles of a regular polygon will always equal 360 degrees To find the value of a given exterior angle of a regular polygon simply divide 360 by the number of sides or angles that the polygon has How To Calculate Interior Angles can I calculate the interior angle of a So to calculate the internal angles of a decagon Draw a regular decagon Mark the centre and draw lines to 2 adjacent vertices Draw a line to the next vertex each side as well Notice that you have a bunch of isosceles triangles that each interior angle is made up of one angle from each pair of adjacent triangles

angles polygons htmlThe Interior Angles of a Quadrilateral add up to 360 Because there are 2 triangles in a square The interior angles in a triangle add up to 180 and for the square they add up to 360 because the square can be made from two triangles How To Calculate Interior Angles
