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.

What is the sum of the measures of the exterior angles in a regular decagon?
The exterior angles of any polygon add up to 360.
What do you call a 10 side polygon?
decagon
What is the size of one interior angle in a regular decagon?
Each interior angle measures 144 degrees
What is the angle measure of each interior angle of a regular decagon?
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
How many vertices and angle does decagon have?
A vertex is the same as an angle. A decagon has 10.A vertex is the same as an angle. A decagon has 10.A vertex is the same as an angle. A decagon has 10.A vertex is the same as an angle. A decagon has 10.
What is the sum of the measures of the interior angles of a decagon?
1440
What is the sum of the measures of the angles of a regular decagon?
1440
What is the sum of the measures the interior angles of a decagon?
1440 degrees
What is the measurement of one angle on a decagon?
Each interior angle of a regular 10 sided decagon measures 144 degrees
What is the sum of the measures of a decagon?
Add each side of the decagon, or all ten sides, to get the sum.
What is the measures of one of the interior angles of a regular decagon?
144 degrees.
Each interior angle of a regular decagon measures?
well the total degrees in a decagon is 1440 therefore each interior angle in a regular decagon would measure 144 degrese
What is the interior angle for a decagon?
Interior angles add up to 1440 degrees Each interior angle of a regular decagon measures 144 degrees
How lines of symmetry does a decagon have?
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.
What is the interior and exterior angle for a regular decagon?
A decagon is a polygon with 10 sides. By using the interior and exterior postulates, you can find the angle measures, which happen to be 144 and 36 degrees respectively.
What is the measure of one interior angle of a regular decagon?
Each interior angle measures 144 degrees
What is the measure of one of the interior angles of the regular decagon?
Each interior angle measures 144 degrees
