The answer depends on what you are trying to measure: interior angles, exterior angles, central angles, lengths of sides, apothems, perimeter, lengths of diagonals, area, etc. And since you have not bothered to share that crucial bit of information, I cannot provide a more useful answer.
Oh, dude, a decagon has 10 sides, right? So, each angle in a regular decagon measures 144 degrees. Now, a right angle is 90 degrees, so technically, there are zero right angles in a decagon. But hey, who's counting, right?
The exterior angles of any polygon add up to 360.
decagon
Each interior angle measures 144 degrees
The angle measure for each interior is 144 degrees each.Explanation: The angle measure of each interior angle of a regular decagon is 144°. Since a decagon is a 10-sided figure, replace n by 10 in (n − 2) • 180°. So the sum of the interior angle measures in a decagon is (10 − 2) • 180°, or 8 • 180° = 1440°. This is a regular decagon, so all ten interior angles are congruent. To calculate the measure of each interior angle in this regular decagon, divide 1440 by 10. The answer is 144°. 144 degrees is equal to 4/5 of 180 degrees
1440
1440
1440 degrees
Each interior angle of a regular 10 sided decagon measures 144 degrees
Add each side of the decagon, or all ten sides, to get the sum.
well the total degrees in a decagon is 1440 therefore each interior angle in a regular decagon would measure 144 degrese
144 degrees.
Interior angles add up to 1440 degrees Each interior angle of a regular decagon measures 144 degrees
A decagon is a polygon with 10 sides. In a decagon, each interior angle measures 144 degrees. An acute angle is an angle that measures less than 90 degrees. Since all the interior angles of a decagon are 144 degrees, there are no acute angles in a decagon.
The sum of the measures of the interior angles of a polygon can be calculated using the formula ( (n - 2) \times 180^\circ ), where ( n ) is the number of sides. For a decagon, which has 10 sides, the calculation is ( (10 - 2) \times 180^\circ = 8 \times 180^\circ = 1440^\circ ). Thus, the sum of the measures of the interior angles of a decagon is 1440 degrees.
None are guaranteed.If it is a regular decagon (convex, with all side lengths equal and all angle measures equal), then there are 10 lines of symmetry.
