to 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.
The sum of the interior angles of a 12 sided polygon add up to 1800 degrees.
All polygons have the same number of sides as angles. So if there are 12 sides, thereare 12 angles.
The sum of the interior angles of a four-sided polygon is 360 degrees.
The name of a 20 sided polygon is Icosagon.
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.
The sum of the interior angles of a 12 sided polygon add up to 1800 degrees.
The interior angles of a 12 sided polygon add up to: (12-2)*180 = 1800 degrees
A 12 sided polygon is a dodecagon
1800 degrees (that is the sum of the internal angles of the 12-sided polygon).
Exterior angles = 360 degrees Interior angles = 1800 degrees
All polygons have the same number of sides as angles. So if there are 12 sides, thereare 12 angles.
