The article describes those steps that led students to the discovery of properties regarding triangles, to the construction of median, perpendicular bisector (axis), and notable points. The approach used is that of Inquiry and Embodied cognition in outdoor context. The activity involved 15 students from a middle school in Trieste, Italy. The results were tested by proposing to the students 5 types of exercises on axis, medians, heights and bisectors and the notable points connected to them. Success rates were averaged and divided those that were subjected to outdoor activities (axis and median) compared to those that were carried out in the classroom (heights and bisectors). A further comparison was made between the success rates in drawing the objects under investigation. Finally, we investigated through Mentimeter the students' appreciation of the outdoor activity. 100% of students found the activity fun and helpful. Several used terms such as “beautiful, joy, happiness”. The 85% of students considered group work to be informative and useful, and the words "interesting, informative, learning" were reported by almost all students.

Abstract
The article describes those steps that led students to the discovery of properties regarding triangles, to the construction of median, perpendicular bisector (axis), and notable points. The approach used is that of Inquiry and Embodied cognition in outdoor context. The activity involved 15 students from a middle school in Trieste, Italy. The results were tested by proposing to the students 5 types of exercises on axis, medians, heights and bisectors and the notable points connected to them. Success rates were averaged and divided those that were subjected to outdoor activities (axis and median) compared to those that were carried out in the classroom (heights and bisectors). A further comparison was made between the success rates in drawing the objects under investigation. Finally, we investigated through Mentimeter the students' appreciation of the outdoor activity. 100% of students found the activity fun and helpful. Several used terms such as “beautiful, joy, happiness”. The 85% of students considered group work to be informative and useful, and the words "interesting, informative, learning" were reported by almost all students.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
