Interior Angle Of A Decagon
Since 1440 10 144 each interior angle in a regular decagon has a measure of 144.
Interior angle of a decagon. A decagon is a 10 sided polygon with 10 interior angles and 10 vertices which is where the sides meet. In terms of the apothem r see also inscribed figure. 36 to find the exterior angle of a regular decagon we use the fact that the exterior angle forms a linear pair with the interior angle so in general it is given by the formula 180 interior angle.
A regular decagon has 10 equal length sides and equal measure interior angles. Also each exterior angle has a measure of 36. Its schläfli symbol is 10 and can also be constructed as a truncated pentagon t 5 a quasiregular decagon alternating two types of edges.
Each angle measures 144 144 and they all add up to 1 440 1 440. The interior angle of a regular decagon is 144 degrees. The formula for this is s.
See exterior angles of a polygon. A regular decagon has all sides of equal length and each internal angle will always be equal to 144. A decagon has 10 sides and 10 angles.
An irregular decagon has sides and angles that are not all equal or congruent. A regular decagon has equal interior angle measures. See interior angles of a polygon.
The sum of the interior angles of a decagon is 10 2 180 1440 in a regular decagon all the angles are congruent at 1440 10 144 is it true that the. We find this by first determining the sum of the interior angles. A decagon has 10 sides sum of the interior angles n 2 x 180 sum of the interior angles 10 2 x 180 sum of the interior angles 1440.
