Interior angle = 140 deg so exterior angle = 40 deg. I am trying to calculate the sum of interior angles of a polygon. The measure of an interior angle of a regular polygon is 135 degrees. Click on make irregular and observe what happens when you change the number of sides the sum of the interior angles of a polygon is given by the formula Therefore the number of sides of the regular polygon is 8.
Notice that the number of triangles is 2 less than the number of sides in each example. What is the measures of each exterior angle of a regular polygon having 18 sides? How many sides does it have? How many rotations did you do? Consider, for instance, the pentagon pictured below.
9-1-Angles of Polygons-Note KEY.pdf - 01 Angles of ... from www.coursehero.com This is what i tried: Read the lesson on angles of a polygon for more information and examples. Remember, take the number of sides minus 2, and multiply by 180! What about a regular decagon (10 sides) ? For an irregular polygon, each angle may be different. When you divide a polygon into triangles. 10 sides, so 8 triangles, so 8 x 180 degrees = 1440 degrees. To generalize our calculation of angle sum, we use the fact that the angle sum of a triangle is degrees.
All regular polygons are equiangular, therefore, we can find the measure of each interior.
