What is the sum of the exterior angles of dodecagon?
360°
What is the Sum of Exterior Angles of a Dodecagon? The sum of the exterior angles of any polygon is always equal to 360° irrespective of the number of sides. Therefore, even in a dodecagon, the sum of the exterior angles is 360°.
What is the sum of exterior angles of a pentagon?
Sum of Exterior Angles in a Pentagon
We know that each exterior angle is supplementary to the interior angle. Therefore, the sum of exterior angles of a polygon = n(360°/n). As, the number of sides in a pentagon is 5, n=5. Thus, the sum of exterior angles of a pentagon = 5(360°/5) = 360°.

Properties of a dodecagon
Here are the properties of a 12-sided shape: Each interior angle of a regular dodecagon is equal to 150°. Each exterior angle of a regular dodecagon is equal to 30°.
What is the sum of the exterior angle?
The sum of the exterior angles of a polygon is 360°. The formula for calculating the size of an exterior angle in a regular polygon is: 360 number of sides. If you know the exterior angle you can find the interior angle using the formula: interior angle + exterior angle = 180°
Are exterior angles always 180?
The sum of an interior angle and its corresponding exterior angle is always 180 degrees since they lie on the same straight line.
What is the sum of exterior angles?
The sum of exterior angles in a polygon is always equal to 360 degrees. Therefore, for all equiangular polygons, the measure of one exterior angle is equal to 360 divided by the number of sides in the polygon.

What polygon has 12 sides and 12 angles?
Dodecagon
A dodecagon is a 12-sided polygon. Several special types of dodecagons are illustrated above. In particular, a dodecagon with vertices equally spaced around a circle and with all sides the same length is a regular polygon known as a regular dodecagon.
Is the sum of exterior angles always 360?
The sum of exterior angles in a polygon is always equal to 360 degrees. Therefore, for all equiangular polygons, the measure of one exterior angle is equal to 360 divided by the number of sides in the polygon. an exterior angle.
What is sum of exterior angles in polygon?
The sum of all the exterior angles in a polygon is equal to 360 degrees.
Why sum of exterior angle is 360?
