Exterior angles of a polygon are formed with its one side and by extending its adjacent side at the vertex. Learn in detail angle sum theorem for exterior angles and solved examples.
When we add up the Interior Angle and Exterior Angle we get a straight line 180°, so they are "Supplementary Angles".PolygonsA Polygon is any flat shape with straight sidesThe Exterior Angles of a Polygon add up to 360°In other words the exterior angles add up to one full revolution....
In order to find the measure of a single interior angle of a regular polygon (a polygon with sides of equal length and angles of equal measure) with n sides, we calculate the sum interior anglesor $$ (\red n-2) \cdot 180 $$ and then divide that sum by the number of sides or $...
The angles of a polygon are the angles between the sides. A regular polygon has equal angles and the sum of the internal angles is given by the formula 180(n-2), where n is the number of sides of the polygon. For example, the sum of the internal angles of a triangle is 180°, ...

Objective:I know how to calculate the interior and exterior angles of polygons. The formula to find the sum of theinterior anglesof any polygon is sum of angles = (n- 2)180° , wherenis the number of sides of the polygon. The sum ofexterior anglesof any polygon is 360º. ...
Sum of exterior angles of a polygon: The sum of exterior angles of any polygon is always 360 degrees. To understand this, we can imagine that we if start moving from one vertex we always move a certain angle and then move the same angle when we reach the next vertex and ...

A polygon is made up of multiple straight lines. When two angles are placed together, they are supplementary angles. These two are your exterior and interior angles. The sum of supplementary angles always equals 180 degrees. When you solve for the exterior angles, all you...
