hey guys, help me out - the angles of an octagon - stratcat - 04-12-2008
someone has to know this.. we're making an octagon out of square steel, for the ends we are goign to cut the angle and then weld it up, each of the angles on the sides of the octagon should be around 40 degrees right? or am I missing something??

Regular Octagons:
The properties of regular octagons:
![[Image: poly-octagon4.gif]](http://www.coolmath.com/reference/images/poly-octagon4.gif)
All sides are the same length (congruent) and all interior angles are the same size (congruent).
To find the measure of the angles, we know that the sum of all the angles is 1080 degrees (from above)... And there are eight angles...
So, the measure of the interior angle of a regular octagon is 135 degrees.

SO the miter cuts on the tubes are 135*/2, right?
