In order to understand the use of triangles in daily life, the teachers and class took a trip to the triangulation point on Hsien Chih Rock in Shihlin to prove the principle that "if you have three fixed points then you can calculate the distance between them."
為瞭解三角形在實際生活中的運用，師生們還跑了趟士林仙芝岩的三角點，證明「只要三點固定就可算出距離」的原理。
