So with any shape look at how many sides you have (for octagon 8 ) and divide 360 by the number of sides (360 degrees makes a complete "trip" around from starting point to end point). 360/8=45.
Next since we are likely wanting to angle the ends of each side, two ends will make up that 45 degree angle. So you divide 45 by 2 = 22.5 degrees.
So to summarize,
Octagon - 360/8 sides/2 = 22.5 degrees
Hexagon - 360/6 sides/2 = 30 degrees
Square - 360/4 sides/2 = 45 degrees

∙ 10y agoA hexagon has six sides and six angles [picture a six sided circle} now a circle has 360 degrees so a hexagon breaks the 360 degrees into 6 angles of 60 degrees each [360 divided by 6 angles] so each angle is 60 degrees but the cuts on each end of the individual sides has to be half of 60 degrees to fit together to form a 60 degree angle. so cut each end at a 30 degree angle. draw a hexagon while reading this and it will be plain as day. same thing for any other shape simply divide 360 degrees by number of sides to get degrees of angles and then halve the angles to get the angle for each end cut.
30 degree angle for each piece.
360 / 6 = 60 60 / 2 = 30 for each of the two pieces
proof: we all know we cut 45's to make a square
360 / 4 = 90
90 / 2 = 45

∙ 11y agoIf you're cutting the wood to make a Pentagon form with a chop saw the degree you're looking for is "36 degrees". Other info on the 5-sided REGULAR Pentagon (all equal sides/all equal angles) are: center angle is 72 degrees, (what is a center angle?) miter angle is 54 degrees (to form a regular pentagon with small wooden pieces I cut 5 identical pieces with 54 degree angles at each end ...only if the pieces are absolutely identical will it form a regular pentagon), and again the bevel is 36 degrees. (also the angle is the same using your table saw with the miter gauge).

What degree cuts do you need to make an equal octagon from wood?
Each exterior angle is 45 degrees (interior angle = 135 degrees).
What length do you need to cut pieces of wood to make an octagon with a circumference of 46 inches?
There is too much extra needed information before an answer can be given. Is the wood to make only the circumference, or would it make all the surface, what is the width of the wood, what design to make the octagon.
