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.
It has six sides and six vertices. It is named so because the word hexagon is made up of two Greek words Hexa and gonia. Hexa refers to six and gonia means angles. A hexagon has six sides and six angles. A regular hexagon has all the sides equal as well as all the angles equal. While, an irregular hexagon does not possess this property. The sum of interior angles of the regular hexagon (six sided polygon) is 720$^{\circ}$ and for exterior angle is 360$^{\circ}$.
