I believe this is because you have added an extra angle (consider interior and exterior angle) which is 180 degrees. But, the sum of the exterior angles must always equal 360 degrees. Therefore the whole 180 degrees must be added to the sum of the interior angles. So every side that is added the sum of the interior angles adds up to 180 degrees. Hope that answers your question.

Antennas provide so called passive gain, which means it comes from particular shape of the antennaThe gain of an antenna is a passive phenomenon - power is not added by the antenna, but simply redistributed to provide more radiated power in a certain direction than would be transmitted by an isotropic antenna. If an antenna has a gain greater than one in some directions, it must have a gain less than one in other directions, since energy is conserved by the antenna.SOURCE: wikipedia.com
