Find the measure of one interior angle of a decagon?

Use the formula "total degrees= 180x(n-2), where n= number of sides of the figure. So, 8x180=1440 degrees, divided by 10 angles=144.

The final part of the above answer is only true if all the angles of the decagon are equal. But there is no justification for assuming that the angles are all equal. In fact, they can have any value in the range (0, 360) degrees with the only restriction being that they add up to 1440 degrees.

What is the interior and exterior angle for a regular decagon?

A decagon is a polygon with 10 sides. By using the interior and exterior postulates, you can find the angle measures, which happen to be 144 and 36 degrees respectively.

Interior angle of a decagon?

To find the interior angle of any polygon. Exterior Angle = 360 / n ( the number of sides) Interior angle = 180 - exterior angle. So for a decagon ( 10 sides) Ext angle = 360 / 10 = 36 Int angle = 180 - 36 = 144.

How do you find the angle of a decagon?

Find any straight side of the decagon. Move along it until it joins another side. That is where an angle is. An angle of a decagon can have any measure between 0 and 360 degrees (except 180 degrees).

A regular decagon is inscribed in a circle find the measure of each minor arc?

To find the measure of each minor arc in a regular decagon inscribed in a circle, we first need to calculate the central angle of the decagon. Since a regular decagon has 10 sides, each interior angle is 144 degrees (180 * (10-2) / 10). The central angle of the decagon is twice the interior angle, so it is 288 degrees. Therefore, each minor arc in the regular decagon inscribed in the circle would measure 288 degrees.

How do you find the interior angle of a decagon?

Its interior angles are: (10-2)*180 = 1440 degrees If its a regular 10 sided polygon then each interior angle is: 1440/10 = 144 degrees
