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.
All hexagons have six sides and six angles. The angles must add up to 720Â°. So it would be possible to have as many as 5 angles equal 90Â° (5 x 90Â° = 450Â°), and one angle equal 270Â° (450Â° + 270Â° = 720Â°). Take a rectangle then cut a rectangular notch at one of the corners. You now have 6 sides and 6 angles.
