# What Sided Shape Has 30 Degree Exterior Angles?

A polygon named “triacontagon” or 30-gon is a thirty-sided polygon. The sum of any triacontagon’s interior angles is 5040 degrees. Each exterior angle is 360/30 deg = 12 deg and each interior angle = 180–12 = 168 deg. A Triacontagon!

One exterior angle of a regular polygon measures 30. What is the sum of the polygon’s interior angle measures? Geometry Angles and Intersecting Lines Angles with Triangles and Polygons.

• Sum of exterior angles = 360 degrees If each one is 12 deg there must be 360/12 = 30 of them. So it is a 30 sided polygon. How many sides does a polygon have if one of the interior angles is 30 degrees?

## Frequently Asked Questions

### What shape has a 30 degree exterior angle?

dodecagonSince all the angles are congruent, 30a=360 , and a=12 . Since a=s , s=12 , so the polygon has 12 sides. (This polygon has a short name: a dodecagon).

### How many sides of exterior angle is 30?

12As it is a regular polygon, all exterior angles are equal and are 30o . Hence number of sides of the polygon is 360o30o=12 .

### What are the exterior angles of a regular polygon with 30 sides?

The sum of exterior angles is always 360. if a regular polygon had 30 sides what is the size for each interior angle? Each EXTERIOR angle is 360/30 = 12 degrees.

### What is the exterior angle of a 30 sided polygon?

Sum of exterior angles = 360 degrees If each one is 12 deg there must be 360/12 = 30 of them. So it is a 30 sided polygon. How many sides does a polygon have if one of the interior angles is 30 degrees?
