Special Segments in Triangles

The Geometry students at Heritage Academy enjoyed their lesson on special segments in triangles.  They took part in a hands on lesson to bring the vocabulary to life. They folded different types of triangles in four different ways to create the special segments. The students used the tools of math in their construction to get the points of concurrency and find their hidden attributes. We found perpendicular bisectors create the circumcenter, which is the center of a circumscribed circle. We found angle bisectors create the incenter, which is the center of an inscribed circle. The medians connect at the center of gravity for the triangle called the centriod. Finally, the altitudes can be in, on, and outside the triangles. The vocabulary of geometry came alive and the folded triangles will make a great study tool for the upcoming test.
