What can you conclude about the angles inside a regular polygon?
Theorem: The sum of the interior angles in a polygon with n sides is 180º(n - 2).In the pentagon below, we have labeled the interior angles 1, 2, 3, 4, and 5. Each of these is supplementary respectively to exterior angles 6, 7, 8, 9, and 10. Therefore we have: We know that angles 1 through 5 in a pentagon have a sum of 540º. We substitute 540º for these angles and we have:. Subtracting 540º from both sides, we can find the sum of the five exterior angles of this pentagon: .

The sum of the interior angles of an n-sided polygon is 180n - 360 degrees.
What is the sum of the internal angles of a pentagon?
The sum of the internal angles of a pentagon is 540 degrees.Here's how:**To find the sum of the internal/interior angles of a polygon there is a formula,(n - 2)180 where n is the number of sides.**n = 5 , a pentagon has 5 sides(n - 2)180(5 - 2)180(3)180540So a pentagon would have 540 degrees. If the formula is too complicated for you to remember, you can use a pattern: Add 180 degrees to the next shape. For example, a triangle has 180 degrees, a quadrilateral has 360 degrees, pentagon has 540, hexagon 720, etc. Each time you add a side you are adding 180 degrees.The sum of the internal angles of a pentagon is 540 degrees.540 degreesThe interior angles in a pentagon total 540 degreesThe sum of the interior angles of a polygon with n sides is equal to 180 x (n - 2). Therefore, the sum of the interior angles of a pentagon is equal to 180 x (5 - 2) = 180 x 3 = 540 degrees.108 degrees.You must work out the exterior angle first.To find exterior, you count the angles on the pentagon, which is 5.And divide it by 360 which you'd get 72 degrees.Now to find the interior, you know a straight line is 180 degrees, so 180 minus 72 which is 108.Viola!360 degreesI vote for 540 degrees.* * * * *There is no need to vote. It can be proven that the interior angles of a polygon with n sides add to (180*(n-2) degrees. For a pentagon that would be 180*(5-2) = 180*3 = 540 degrees.The 5 interior angles of a pentagon add up to 540 degreesTotal interior angles of a pentagon (360+180) = 540 degrees.A pentagon can be divided into a square and a triangle.

If there a formula for finding the measure of an interior angle of a regular polygon?
Yes there is. You find the sum of the interior angles and then divide by the number of angles. Since being regular tells us that every interior angle has the same measurement, this works.Now to find the sum of the interior angles, let n be the number of sides, the the sum is180 degrees (n-2)For example, a triangle has 3 sides so n is 3 and the sum of its interior angles is 180(3-2) or 180 degreesA square has 180(4-2) or 360 degrees as the sum of its interior angles.A regular pentagon has 180(5-2)=180(3) degrees as the sum of the interior angles.Back to the triangle, since the sum is 180 degree and there are 3 angles, each on has measure 60. Similarly for a square, 360 divided by 4 is 90 and each interior angle has measure 90.
How to find interior angle of a regular polygon?
You use the fact that the sum of the interior angles of a regular polygon with n sides is:180(n-2) degreesNow you have the sum of measures of all the interior angles so divide that by n and you have the measure of each interior angle.
