The Twelve  houses of the horoscope define twelve areas of our life.  The beginning of each of the houses is called it cusp.  Each house has what is called a natural ruling sign and natural ruling planets.  That is the sign and planet that is associated with that house in the natural chart that begins with Aries and ends with Pisces.

The Astrodienst charts show another division of the houses.  This division places the houses in groups that are on the angles, the angular (ang).  Houses that follow immediately, the succedent (suc) houses, and the third in line, the cadent (cad) houses. There are four each, angular, succedent, and cadent houses. Older books taught that planets in the angular houses were somewhat stronger and planets in the cadent houses were weaker in influence. Now little attention is paid to this.

Here are listed the twelve houses with the rulerships, classification and a brief summary of the area of life depicted there:
