The cardioid has interested mathematicians for years. Investigating the cardioid along with other Mascheroni constructions became a fascinating adventure for me and for my classroom students! The following paper shows eleven constructions that can be used in the high school or college classroom to study mathematics along with inspiring fascinating designs. The unusual constructions will add interest, variety, and challenge to students.
