A decagon is a polygon with 10 sides and 10 angles. The sum of the interior angles of a decagon is always 1440 degrees. The formula to find the sum of the interior angles of a decagon is:
Sum of interior angles = (n-2) * 180
where n is the number of sides of the polygon.
To find the measure of each interior angle of a regular decagon, we use the formula:
Measure of each interior angle = Sum of interior angles / Number of sides
For a decagon, the measure of each interior angle is 1440 / 10 = 144 degrees.
A regular decagon has all sides and angles equal. An irregular decagon has sides and/or angles that are not all equal.
Find the measure of each interior angle of a regular decagon.
Measure of each interior angle = 1440 / 10 = 144 degrees.
Therefore, the measure of each interior angle of a regular decagon is 144 degrees.
Now that you understand the properties and formulas related to decagons, you can practice solving problems and identifying decagons in different geometric figures.
Good luck with your studies!
