How do you find the exterior angle of a polygon?
360/number of sides 180 times the number of sides the polygon has then minus 360. This gives the total sum of the exterior angles. Then to get the angle of one exterior angle divide it by the number of sides the polygon has.Very easy when you know the formula!
What is exterior angle sum theorem polygon?
No matter how many sides a convex polygon has, the sum of its exterior angles is 360°.
How do you find the number of sides a regular poly gon has by knowing the angles?
When a polygon is regular, each exterior angle is equal to the other exterior angles. Since the sum of all the exterior angles is 360 degrees, if you divide 360 by the measure of one exterior angle, you will get the number of sides. If you instead have the measure of an interior angle, simply calculate (180 - interior angle measure) to find the measure of the exterior angle, and use the above paragraph.
What is the formula to find the sum of the measures of the exterior angles one at each vertex of a polygon?
If it's a regular polygon: 360/number of sides = each exterior angle
How do you find how many sides of a polygon has with the measure of an exterior angle?
The sum total of all exterior angles of any polygon is 360 degrees. So if you're given thevalue of one exterior angle AND THE POLYGON IS REGULAR(all exterior angles are thesame size), all you have to do is divide the size of one angle into 360, and the quotientis the number of sides.

What is the sum of the exterior angle of a heptagon?
The sum of the exterior angles of an n-gon is 360 degrees, however many sides it has.
What is exterior angle sum theorem polygon?
No matter how many sides a convex polygon has, the sum of its exterior angles is 360°.
What is the exterior angle sum of a trapezoid?
The exterior angle sum of ANY plane polygon (ie 2-dimensional figure with straight sides) is 360 degrees.
One exterior angle of a regular polygon measures 30 what is the sum of the polygons exterior angle measures?
If the exterior angle is 30o then the shape has 360/30 = 12 sides. An interior angle = 180 - exterior angle = 180 - 30 = 150. Since the shape has 12 sides the interior angles sum to 150 x 12 = 1800o.
A convex polygon has 7 sides and one angle at each vertex Whats is the sum of exterior angles?
The sum of the exterior angles of a convex polygon which has sides and one angle at each vertex is 360 degrees.

What is the exterior angle sum of regular heptagon?
The exterior angle sum is 360 degrees. It doesn't matter whether the polygon is regular or not, and it doesn't even matter how many sides it has.

If it's a regular polygon: 360/number of sides = each exterior angle
How to Find the sum of the interior angle measures and the sum of the exterior angle measures of a quadrilateral?
360 degrees

One angle of polynomial is 144 degree.find no of sides of polynomial?
The sum of the exterior angles of a polygon is 360o. Dividing 360o by the size of the exterior angle gives the number of sides. If the interior angle is 144o, the exterior angle is 180o - 144o = 36o. Number of sides = 360o / 36o = 10 (a decagon).
