T-square

Definition

A t-square is a configuration of three planets where two of them sit in opposition and a third sits in square to both, forming a right-angled triangle across the chart. The third planet, the apex, receives a double load of tension because it absorbs the pressure of both ends of the opposition. The t-square reads as a high-energy figure that drives the chart forward through friction.

In context

If natal Mars at fifteen degrees of Aries opposes natal Saturn at fifteen degrees of Libra, and natal Pluto sits at fifteen degrees of Capricorn squaring both, the chart carries a cardinal t-square with Pluto at the apex. The apex planet usually becomes the focal point of the configuration, the function the life keeps returning to because the tension of the opposing pair keeps insisting on resolution.

To go deeper

The t-square belongs to the family of three-planet configurations:

• Configuration: umbrella term for the family.
• Grand trine: three-trine triangular figure.
• Yod: two-quincunx, one-sextile figure.
