The sesquiquadrate (abrv. Ses) is an angle of 135° (a square [90°] + a semisquare [45°]). A separation of 135±2° is considered a sesquiquadrate; it indicates somewhat stressful conditions. it is considered similar in influence to the semisquare. The sesquiquadrate is sometimes called a sesquisquare, square-and-a-half, quartile-and-a-half, and/or trioctile.

The sesquiquadrate is equivalent to a square plus a semisquare, and so it is 135 degrees. The interpretation of the sesquiquadrate is much the same as that of a semisquare, which is considered to be like a square. This aspects is also called a trioctile. If there are no squares present, the semisquares or sesquiquadrates takes on a stronger force.
