The twelve houses reflect the meanings of the twelve signs and are grouped into three Quadratures of their own: angular, succedent, and cadent.
An Angular house sits on an angle. The angles are the four cardinal points of the chart: Ascendant, Descendant, Midheaven, and Nadir. Planets located inn these houses are tradationally held to be strengthened by this position. This is also known as "accidentally dignified." The angular houses are the First, Fourth, Seventh, and Tenth House, corresponding to the Cardinal signs.
Planets placed within Succedent houses are neither strengthened nor weakened. The Succedent houses are the Second, Fifth, Eighth, and Eleventh houses, and correspond to the Fixed signs.
Planets within Cadent houses are traditionally held to be weakened, or "accidentally debilitated." This is true for all but the natural rulers of the cadent houses: Mercury in the Third and Sixth houses, Jupiter of the Ninth house, and Neptune of the Twelfth house. These correspond to the Mutable signs.
