Only partially correct. The above is the number of right angles. So the correct answer is 20*90 = 1800 degrees.

What is the interior angle of a dodecagon?

The interior angle of a dodecagon is not 1260 that is of a nonagon * * * * * The interior angle of a dodecagon can have any value in the range (0, 360). The only restriction is that the sum of all 12 interior angles (which need not be equal) is 1800 degrees.


The sum of the interior angle measures of a dodecagon is what?

The interior angles of a 12 sided dodecagon add up to 1800 degrees


What is the measure of an angle of a regular dodecagon?

Interior Angle: 150 degrees (Interior Angle Sum: 1800) Exterior Angle: 30 degrees (Exterior Angle Sum: 360)


What are the interior angle measures of a dodecagon?

The sum of the interior angles of a dodecagon is:sum = (12 - 2) x 180o= 1800oIn a regular dodecagon, each of the interior angles is 1800o ÷ 12 = 150o


What is the measure of dodecagon?

The interior angles of a dodecagon sum to 1800 degrees.


What is the interior angle of a regular dodecagon?

Each interior angle measures 144 degrees* * * * *No! The sum of the exterior angles of a polygon is always 360 degrees - no matter how many sides, So the extrior angle of a regular dodecagon is 360/12 = 30 degrees. Since the interior and exterior angles are supplementary, the interior angle is 180-30 = 150 degrees.


What is the mesure of one interior angle of a regular dodecagon?

Each interior angle of a regular 12 sided dodecagon measures 150 degrees


Vertex angle of regular 12 gon measures 144 degrees?

No: The sum of the exterior angles of a polygon is 360o. For a dodecagon (12 sides) the exterior angle is 360o / 12 = 30o. The interior and exterior angles are supplementary and so they sum to 180o; thus the interior angle of a dodecagon is 180o - 30o = 150o. For an interior angle of 144o, the exterior angle is 180o - 144o = 36o, so there are 360o / 36o = 10 sides (a decagon).
