great for the kids to summarize the concurrency points
Recommended for: Geometry, GeometryGizmo User from Florida
Great for teaching Points of Concurreny in Triangles. Correlates to Georgia Math I GPS
Recommended for: GeometryGizmo User from Georgia
It shows the students what happens to the points of concurrency as the triangle changes. No need to do multiple constructions
