Well hello there, friend! A 12-sided polygon is called a dodecagon. To find the sum of the interior angles in any polygon, you can use the formula (n-2) x 180 degrees, where n is the number of sides. So, for a dodecagon, the sum of the interior angles would be (12-2) x 180 = 1800 degrees. Each interior angle in a dodecagon would be 1800 degrees divided by 12, which equals 150 degrees. Happy painting!

Laoto calculate this, you must find out how many triangles you can draw in to the shape. do this by picking an angle. draw a line to all of the other angles. (for a 12 sided, there would be 9, subtract 3 from any shape to see.) mutiply the number of triangles by 180 degrees. this should be the degrees of the shape. for a 12 sider, the answer would be 1620 degrees.

What is the sum of the measure of the interior angles of a 12-sided polygon?
The sum of the interior angles of a 12 sided polygon add up to 1800 degrees.
How many angles are in a 12 sided polygon?
All polygons have the same number of sides as angles. So if there are 12 sides, thereare 12 angles.
What is the sum of the angles of a four-sided polygon?
The sum of the interior angles of a four-sided polygon is 360 degrees.
What are the angles of a 20 sided polygon?
The name of a 20 sided polygon is Icosagon.
What is the measure of an exterior angle of a twelve sided polygon?
If the 12-sided polygon is 'regular', then each of its exterior angles is 30 degrees. Whether the polygon is regular or not, all 12 of its exterior angles still add up to 360 degrees, but they may not all be equal.
