Geometry students often wonder about the importance of construction techniques. Are they the only way to create geometric figures? What purpose do they serve? How do these techniques relate to other parts of geometry? This article introduces a project used at the high school level that gets all students in a class engaged with construction, gets them thinking creatively and mathematically, and gives them a sense of satisfaction when they master the ideas behind construction. This project, based on the ancient geoglyphs of the Nasca culture, offers students engagement with construction techniques, the chance to think creatively, and a sense of satisfaction when they master the ideas behind construction.
