T-Squares Study
The T-Squares Study generates an event whenever three transiting bodies form a T-Square: two of the three are in opposition and the third is square (90°) the other two, within a user-defined pattern orb.

You can also create a T-Squares Study from the toolbar by clicking the Aspect Patterns drop-down button and selecting T-Squares.
Events Captured
A T-Squares event occurs when two transiting bodies are in opposition (180°) and a third transiting body is square (90°) to the first two, all within the user-defined pattern orb. The study reports the moment of tightest configuration.
Events Table Columns
The events table for a T-Squares Study contains the following columns:
| Column | Description |

| Body1 | Name of the first body in the T-Square pattern. |
| Body1 Longitude | Ecliptic longitude (or right ascension) of Body1. |
| Body1 Sign | Zodiac sign of Body1. |
| Body1 Latitude | Ecliptic latitude (or declination) of Body1. |
| Body1 Distance | Distance of Body1 from the coordinate origin. |
| Body1 Speed | Apparent angular speed of Body1. |
| Separation Body(1-2) | Angular separation between Body1 and Body2 (one of the squares of the T-Square). |
| Body2 | Name of the second body in the T-Square pattern. |
| Body2 Longitude | Ecliptic longitude (or right ascension) of Body2. |
| Body2 Sign | Zodiac sign of Body2. |
| Body2 Latitude | Ecliptic latitude (or declination) of Body2. |
