The sum of the interior angles (the angles of a polygon is equal to the 180*(n-2), where n is the number of sides. For example, if a polygon has 5 sides the sum of the angles is 180*(5-2), which is 540 degrees. The sum of the exterior angles (the angles on the outside of the polygon made by extending a side and measuring the angle between the extension and the nearest side) is always equal to 360 degrees.
The sum of the interior angles of any regular polygon of n sides is equal to 180(n - 2) degrees.
The sum of the external angles of any regular polygon is equal to 360. Therefore, a single exterior angle of an icosagon is 360/20 = 18 degrees.
an angle that forms a linear pair with one of the interior angles of the trinagle.(Apex)
If the sides and angles are equal, yes. Otherwise, no.
Square or rectangle
No because an exterior angle and an interior angle of a polygon add up to 180 degrees but exterior angles around a polygon add up to 360 degrees
4 such as a square
When all sides are equal and all interior and exterior angles are equal.
That's true of any polygon with four sides.
Interior angles are equal and sides are equal in length and exterior angles add up to 360 degrees
The total of the interior angles equal 5040, and each angle measures 168 degrees The total of the exterior angles equal 360, and each angle measures 12 degrees
The sum of the exterior angles of a polygon is equal to 360 degrees.
The sum of the exterior angles of all polygons equals to 360⁰.Since only the sum of the interior angles of all quadrilaterals equals to 360⁰, the polygon must have 4 sides.
