Now, the area of a triangle is half of the base times height, so: Area of one triangle = base Ã height / 2 = side Ã apothem / 2. To get the area of the whole polygon, just add up the areas of all the little triangles (n of them): Area of Polygon = n Ã side Ã apothem / 2. And since the perimeter is all the sides = n Ã side, we get: Area of Polygon = perimeter Ã apothem / 2.
Intense interest if your cat is focusing on something, like a bird outside, or if heâs about to pounce on a toy (prey). Ecstasy if your cat is really enjoying a grooming session. Anger if the tail is thumping loudly on the floor. An invitation to another cat to play.
Following are some insights into what your cat is 'saying' with its tail. 1. Tail curves gently down and then up again at the tip. Cat is relaxed and all is well in his world. 2. Tail slightly raised with a soft curve. Something has peaked the cat's interest. 3. Tail is held erect but the tip is tilted over. Cat is in a friendly mood with slight reservations. 4. Tail fully erect with the tip stiffly vertical. This is a wholehearted greeting with no reservations. This is a carry-over from the kitten stage when greeting mom and inviting her to inspect the kitten's rear end.
