This free centers of triangles graphic organizer reviews the four points of concurrency: circumcenter, incenter, centroid, and orthocenter. Each center includes a labeled diagram along with space for students to record what it is created by and important facts about it, so all of the concepts are organized together in one place.
How It Works:
Students fill in how each center is formed (perpendicular bisectors, angle bisectors, medians, or altitudes) and complete the important facts for each one. Seeing all four centers side by side helps students compare and contrast them, and the finished organizer makes a great reference for notes, homework, and review before a quiz or test.
This organizer works very well with Geometry Unit 5: Relationships in Triangles.
