5. What is the measure of one of the exterior angles in a regular convex 18-gon?
360 / 18 = 20 degrees
the sum of exterior angles in all polygons add up to 360
what is the meaning of gon
thank you :)
That is totally false.
gon a in polygon means sides poly = many. many sides
In a n-gon, the interior angle is equal to (180(n-2))/n °. The exterior angle is 360° minus the interior angle. So, in a 18-gon the interior angle is 160° and the exterior is 200°.
it depends what you mean by the exterior angle, but in Geometry it is taken to mean the angle between one side of the polygon and the adjacent one extended outside the polygon
An exterior angle beta of a polygon is the angle formed externally between two adjacent sides. It is therefore equal to 2pi-alpha, where alpha is the corresponding internal angle between two adjacent sides (Zwillinger 1995, p. 270).
as i said - there are two definitions
in euclidian geometry its the other definition
satellite, wen ur done here can u help me wit my questoin?
