If you have a Lease, you should look to when the month-to-month obligations are effective. If it states that you pay on a calendar month basis, then your notice will be considered as being more that the required 30 days, and that you owe for the full following month.
A regular polygon is equiangular, which means all angles are the same measure. In the case of a regular hexagon, the sum of 720 degrees would be distributed evenly among the six sides. So, 720/6 = 120. There are six angles in a regular hexagon, each measuring 120 degrees.
An alternated hexagon, h{6}, is a equilateral triangle, {3}. A regular hexagon can be stellated with equilateral triangles on its edges, creating a hexagram. A regular hexagon can be dissected into 6 equilateral triangles by adding a center point.
