What is the sum of the exterior angles of a undecagon?

All polygons, including an undecagon (11-sided figure) have a sum of exterior angles of 360 degrees.


What is the sum of the measure of interior angles for a 31 gon?

Its 31 interior angles will add up to 5220 degrees


What is the measure of the convex 41- gon?

The answer depends on what you wish to measure: the area, the number of sides, the number of vertices, the sum of the interior angles, the sum of exterior angles, ... The question is hopelessly underspecified.


If there a formula for finding the measure of an interior angle of a regular polygon?

Yes there is. You find the sum of the interior angles and then divide by the number of angles. Since being regular tells us that every interior angle has the same measurement, this works.Now to find the sum of the interior angles, let n be the number of sides, the the sum is180 degrees (n-2)For example, a triangle has 3 sides so n is 3 and the sum of its interior angles is 180(3-2) or 180 degreesA square has 180(4-2) or 360 degrees as the sum of its interior angles.A regular pentagon has 180(5-2)=180(3) degrees as the sum of the interior angles.Back to the triangle, since the sum is 180 degree and there are 3 angles, each on has measure 60. Similarly for a square, 360 divided by 4 is 90 and each interior angle has measure 90.


What is the sum of the angles of a polygon with 102 sides?

The sum of the interior angles is (102-2)*180 = 18,000 degrees.The sum of the interior angles is (102-2)*180 = 18,000 degrees.The sum of the interior angles is (102-2)*180 = 18,000 degrees.The sum of the interior angles is (102-2)*180 = 18,000 degrees.
