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.
What does it mean when your cat waves its tail? Wouldnât it be great if you could talk to your cat and know what it was feeling? Well, by reading simple body language you can! By taking note of what the tail ears and fur on your cat is doing you can see how he or she is feeling, writes Gordon Bloomfield.
