In other words the exterior angles add up to one full revolution.Press Play button to see.(Exercise: try this with a square, then with some interesting polygon you invent yourself.)Note: This rule only works for simple polygons.We can also think "each line changes direction until we get ...
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.
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. Read the...

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 when we reach the last vertex, we co...
Triangles: Interior and Exterior Angles Main Concept An interior angle of a polygon is formed by two sides of a polygon that share an endpoint. A shape has one internal angle per vertex . For a triangle, an interior angle is the angle between any two...

A rule of polygons is that the sum of the exterior angles always equals 360 degrees, but lets prove this for a regular octagon (8-sides).First we must figure out what each of the interior angles equal. To do this we use the formula:...
