Sum Of Interior And Exterior Angles Worksheet The sum of the exterior angles is found by subtracting the sum of the measures of the interior angles from the sum of the measures of the linear pairs at the vertices Step 5
Find the interior and exterior angles of a regular dodecagon 6 An octadecagon is a polygon with 18 sides Find the interior and exterior angles of a regular octadecagon 7 An icosagon is a polygon with 20 sides Find the sum of the interior angles in a regular icosagon In any polygon the sum of an interior angle and its corresponding exterior angle is 180 176 That is Interior angle Exterior Angle 180 176 Interior angle 40 176 180 176 Interior angle 140 176 So the measure of each exterior exterior angle of a regular nonagon is 140 176

What is the sum of the measures of the exterior angles of any polygon 1 Count the number of sides in the polygon Record this number in your table 2 Pick a vertex Draw diagonal lines from this vertex to every other non adjacent vertex to create triangles Count how many triangles you have created An angle that is inside a shape is known as an interior angle Since triangles have three sides there can only be three interior angels It is important to note that the sum of three interior angles a b c is always equal to 180 degrees
