What is a T-square?
Two planets in opposition (180°) that both square (90°) a third, called the apex. The apex is where the tension of the opposition is felt and worked out, and the tradition reads the whole figure as a chart’s engine: friction that drives effort and achievement.
Where astrologers disagree
The orb, and whether a figure whose signs are not all of one modality still counts, are conventions. Here a T-square is an opposition and two squares the chart already shows, between planets.
