Interior Angle Sum Of A Decagon

An irregular decagon has sides and angles that are not all equal or congruent.

Interior angle sum of a decagon. A regular decagon has 10 equal length sides and equal measure interior angles. In geometry a decagon from the greek δέκα déka and γωνία gonía ten angles is a ten sided polygon or 10 gon. A regular decagon has equal interior angle measures.

A self intersecting regular decagon is known as a decagram. Since 1440 10 144 each interior angle in a regular decagon has a measure of 144. 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.

So the sum of the interior angles of a decagon is 1440 degrees. The total sum of the interior angles of a simple decagon is 1440. Part b what is the measure of each interior angle of a regular decagon.

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 what is the sum of. In this problem regular decagon. Sum of interior angles n 2 180 each angle of a regular polygon n 2 180 n.

N is the number of sides of a polygon. A decagon is a 10 sided polygon with 10 interior angles and 10 vertices which is where the sides meet. A decagon has 10 sides and 10 angles.

If the figure is a regular polygon then all interior angles are equal. Also each exterior angle has a measure of 36. Each angle measures 144 144 and they all add up to 1 440 1 440.
