To find the interior angles of a 25-sided polygon (icosikaipentagon), you can use the formula for the sum of interior angles, which is ( (n - 2) \times 180^\circ ), where ( n ) is the number of sides. For a 25-sided polygon, this calculation would be ( (25 - 2) \times 180^\circ = 23 \times 180^\circ = 4140^\circ ). To find the measure of each interior angle in a regular 25-sided polygon, divide the total sum by the number of sides: ( \frac{4140^\circ}{25} = 165.6^\circ ).

What is the total interior angle for a 979 sided shape?
The equation for the total interior angles of a polygon is (n-2)x180. In this case, the shape has 979 sides. Thus, to work out the total interior angles of the shape you do: (979-2)x180 =977x180 =175,860 Therefore the total interior angles for a 56 sided shape is 175,860.
How do you work out an interior angle on a polygon?
For any REGULAR n-sided polygon the interior angles are (180 - 360/n) degrees eg for a regular octagon, where n = 8, the calculation is 180 - 360/8 ie 180 - 45 = 135o degrees.
How can you determine the sum of the interior angles of a hexagon justify your answer?
The sum of the interior angles of any n-sided figure is (2n - 4) right angles. When n = 6 this equates to 8 x 90 ie 720o. Consider an n-sided polygon. From any point A inside the polygon draw a straight line to each vertex, thus creating n triangles. (As the final formula is based on right angles, we work on right angles from here.) Each triangle contains 180o, ie two right angles, so the sum of the angles of all the triangles is 2n right angles. The angles round the point A form a complete revolution, ie 360o, which is four right angles, which are not part of the interior angles of the polygon. These interior angles therefore total (2n -4) right angles.
How do you work out an interior angle on a polygon when it has n sides?
The sum of the interior angles of a polygon with n sides is 180*(n-2) degrees. If the polygon is equiangular (ie all its angles are the same) then each of them is 180*(n-2)/n degrees.
How do you work out interior angles of an irregular polygon?
A regular or irregular polygon is a plane shape with straight sides.Measure the internal angle of all corners using a protractor.
What is the total interior angles for a 56 sided shape?
The equation for the total interior angles of a polygon is (n-2)x180. In this case, the shape has 56 sides. Thus, to work out the total interior angles of the shape you do: (56-2)x180 =54x180 =9,720. Therefore the total interior angles for a 56 sided shape is 9,720.
Work out the exterior and interior angles of a regular polygon with 15 sides?
The sum of the exterior angles of a polygon is 360o, so for a regular n-sided polygon, each is 360o/n. The interior and exterior angles of a polygon are supplementary, that is sum to 180o. For a regular 15 sided polygon: exterior_angle = 360o / 15 = 24o interior_angle = 180o - exterior_angle = 180o - 24o = 156o Alternatively: The sum of the interior angles of a n-sided polygon is (n-2) x 180o, so for a regular n-sided polygon each interior angle is (n-2) x 180o / n. For a 15 sided polygon: interior_angle = (15 - 2) x 180o / 15 = 13 x 12o = 156o exterior_angle = 180o - interior_angle = 180o - 156o = 24o.

What is the sum of the measures of the interior angles of a 5 sided convex polygon?
Use this form to work out the problem: (n - 2)180° where n is the number of sides Suppose that we have a regular polygon. This is the example of a convex polygon. Given that we have a 5-sided convex polygon, we obtain: (5 - 2)180° = 3 * 180° = 540°
How do you work out an interior angle on a polygon?

How do you work out how many sides a polygon has from the sum of the interior angles?
Sum of interior angle of n-sided polygon always = (2n - 4) right angles or 180n - 360 degrees. n therefore = (known total + 360)/180 eg if the known total is 540 degrees, n = (540 + 360)/180 ie 5.
How do you work out an interior angle on a polygon when it has n sides?
The sum of the interior angles of a polygon with n sides is 180*(n-2) degrees. If the polygon is equiangular (ie all its angles are the same) then each of them is 180*(n-2)/n degrees.
How do you work out the angles in a polygon?
There is no way to work out the angles in a general polygon. The sum of the interior angles of a polygon, with n sides, is (n-2)*pi radians [or (n-2)*180 degrees]. Therefore, if you know the measure of n-1 angles, you can work out the size of the nth angle.Alternatively, if the polygon is one of the rare type - a regular polygon - then all its angles are equal. In that case, you can divided the above sum by n.
What is a 102 sided polygon?
Oh, what a happy little question! A 102 sided polygon is called a "hectacontadigon." Just imagine all those lovely angles and sides coming together in perfect harmony to create a beautiful shape on your canvas. Remember, there are no mistakes, just happy little accidents in the world of polygons.
How do you work out interior angles of an irregular polygon?
A regular or irregular polygon is a plane shape with straight sides.Measure the internal angle of all corners using a protractor.
How do you work out the exterior angles of a pentagon?
Exterior angles of ANY regular n-sided polygon are 360/n degrees. Where n is 5 this gives 72 deg.
