Exterior Angles in Regular Polygons<\/h5>\n[\/vc_column_text][\/vc_column_inner][\/vc_row_inner][vc_column_text el_class=”headingnew”]Concept[\/vc_column_text][vc_column_text]An exterior angle<\/strong> of a polygon is the angle that is formed between any side of the polygon and a line extended from the next side. Every polygon has interior and exterior angles. The exterior is the term opposite to the interior which means outside. Therefore exterior angles can be found outside the polygon. The sum of the exterior angles of any polygon is equal to 360\u00b0. Any flat shape or figure is said to have interior or exterior angles only if it is a closed shape.<\/p>\n

\"\"<\/a>[\/vc_column_text][vc_column_text el_class=”headingnew”]Rules[\/vc_column_text][vc_column_text]The sum of the exterior angles of every polygon is 360 degrees.<\/p>\n

The measure of one of the exterior angles of a regular polygon can be found by dividing 360 degrees by the number of angles (n<\/strong>).<\/strong><\/p>\n
