Each exterior angle of a regular 5 sided pentagon is 72 degrees.
The five interior angles of a regular pentagon are all 72º. For each angle to be closed, one of the arms must travel through 360 - 72 degrees. So the exterior angles of a regular pentagon are 360 - 72 = 288º
pentagon because it has an obtuse angle and a square has right angles- Actually, a regular pentagon has larger interiorangles, however, for exterior angles, a square beats a regular pentagon, because all exterior angles of a shape equals 360 degrees. A square has 4 angles, and 360/4= 90. A regular pentagon has 5 angles, and 360/5=72. If the pentagon isn't regular, then one exterior angle can be larger than 90 degrees.
Exterior angle of any regular n-sided polygon is 360/n degrees, in this case n = 5 so 72o
One interior angle of a regular 5 sided pentagon measures 108 degrees.
The measure of one angle of a regular pentagon is 108 degrees.
Each exterior angle of a regular octagon: 360/8 = 45 degrees
360/6 = an exterior angle of 60 degrees
