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.
Hexagon may either be convex or concave. If a hexagon is said to be convex, the sides are of the same length also known as equilateral. Thus, it is a regular hexagon. To identify how many sides does a hexagon have, just count the line segment or sides that makes it as a whole closed figure. A good example of a hexagonal figure is the shape of the honeycomb and try also looking or searching in the internet, the figure inside a gear is a hexagonal one.
