👉 In geometry, a trisectrix is a quadrilateral with vertices at the three points of intersection of the medians of a given quadrilateral. It is named after the Greek mathematician Euclid who introduced this concept in his Elements book. The trisectrix can be considered as a special case of a circumscribed quadrilateral, where each median divides it into four smaller quadrilaterals (also known as triangles). The trisectrix is also related to the trisection
