There are 1440 degrees in a decagon.
To find the sum of the angles in a polygon, you use the formula n-2 multiplied by 180, where n is the number of sides the polygon has.
1440 degrees are the interior angles.
The 10 interior angles of a decagon add up to 1440 degrees
A decagon has 10 sides, and 10 angles. 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°
The interior angles of a 10 sided decagon add up to 1440 degrees.

The exterior angles of any polygon always add up to 360 degrees
The 10 interior angles of a decagon add up to 1440 degrees
Add each side of the decagon, or all ten sides, to get the sum.
A decagon has 10 sides, and 10 angles. 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°

The sum of the interior angles of a decagon is 1440 degrees The sum of the interior angles of a triangle is 180 degreesThe difference in the sum of the interior angles of a decagon compared to a triangle = 1440 degrees minus 180 degrees = 1260 degrees
The 10 interior angles of a decagon add up to 1440 degrees
