A student brushes on glue to sturdy his bridge design.
MASON, OH -- Mars Hill Academy ninth grade geometry students applied their understanding of triangles to the building of bridges.
After exploring angles and sides, the relationship between congruent and similar triangles, proofs concerning triangles, and some right triangle trigonometry, they put these principles to the test. For this project, students create a design, estimate construction costs, build the bridge out of toothpicks and glue, present to the class, and then stress test their bridges.
