A bevel is an angle cut into the edges of the insulation panels. When you buy them, all of the edges are cut at right angles, i.e. 90º. In geometry, all the angles of any 3-dimensional object must add up to 360º. So if you add up the four 90º angles of an insulation panel (two on each edge because a panel is basically a long, thin rectangle) you get 360º.
When you build a hexayurt, the wall panels stand straight up so their angle with the ground is 90º. Then you have the two angles on each side where the walls meet the roof and the angle at the top ridge of the roof, which are all 60º. Add them together and you get (90 + 90 + 60 + 60 = 60 = 360º) But wait, those 60º angles on the junction of the walls and roof and peak of the roof are where two panels meet, so each panel needs a bevel of 30º, which will equal 60º when the panels are taped together. You can cut the bevels with a box cutter and just guesstimate the angles, or more accurately cut them by setting the blade of a Skilsaw to 30º. My point in my previous comment is that beveling the edges before taping makes a much stronger yurt because any load (usually wind, but maybe somebody stumbling and falling against the yurt) will be transferred to the ground. Without bevel cuts on the edges of the walls and roof increases the risk of your yurt collapsing or becoming a kite. This project may be a bit difficult for you if you don't understand bevels and 3-dimensional geometry.
