Each exterior angle = 360/12 = 30 degrees.

Each interior angle = 180 - 30 =150 degrees.

What is the exterior angle of a regular dodecagon?

For any given polygon, the exterior angles will sum to 360 degrees. Thus, for a regular polygon, dividing by the number of exterior angles (the same as the number of sides) will produce the exterior angle. For a dodecagon (12 sides), 360/12=30 degrees. You can also find the interior angle easily because the interior and exterior angles are supplementary: 180-30=150 degrees for an interior angle.


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.


Which regular polygon the measure of the exterior angle is twice the measure of the interior angle?

In a regular polygon, the measure of the exterior angle is related to the interior angle by the equation: exterior angle = 180° - interior angle. If the exterior angle is twice the measure of the interior angle, we can set up the equation: exterior angle = 2 × interior angle. Solving this gives us the equation: 180° - interior angle = 2 × interior angle, leading to 180° = 3 × interior angle, or interior angle = 60°. This corresponds to a regular hexagon, as it has interior angles of 120° and exterior angles of 60°.


What is the measure of each exterior angle of a regular dodecagon?

For the 12-sided polygon, each exterior angle is 30 degrees (360/12).


What is the shape of the twelfth figure?

The shape of the twelfth figure is a dodecagon. A dodecagon is a polygon with twelve sides and twelve angles. It is a regular dodecagon if all its sides and angles are equal. The interior angles of a regular dodecagon measure 150 degrees each.


How can you get the measure of an interior angle if you have the measure of the exterior angle of a regular polygon?

It is: 180-exterior angle = interior angle because there are 180 degrees on a straight line
