Gestation or the length of pregnancy of a cat averages 64 days. It is generally between 62 and 67 days or about nine or ten weeks. When litters are large, length is often less. When litters are small, the length of the pregnancy may increase.
The sum of the interior angles of an octagon is 1080 degrees. In a regular octagon, divide by 8 for each angle = 135Â°. The formula for this is Sum = 180 (n-2) where n is the number of sides. (or 180n - 360) You can take the polygon and make [N] triangles, with points touching at the 'center'.
In geometry, any polygon with ten sides and ten angles and ten vertices is called as Decagon. The sum of angles in a decagon is 1440Â°. In real life, Decagon shape can be seen in few coins, tiles and mugs. 2 Peso Coin of the Republic of the Philippines has a decagon shape. The number of diagonals in a polygon is given by the formula n(nâ3)2.
