A 135° angle — a square plus a semi-square, and another of Kepler's additions. It carries the square's friction but points outward: where the semi-square holds tension in, the sesquiquadrate spills it into circumstances and other people. Traditionally read as the later, more exposed half of a tension cycle.
A sesquiquadrate transit grates rather than grinds. The pressure on the natal point arrives from outside — an interruption, a demand, another person's timing — and asks to be handled through action rather than endured.
Transit Mars sesquiquadrate natal Saturn tends to arrive as an external obstruction — the delay is someone else's, and the frustration is yours to work off.
